HD74HC4520 Dual BCD Up Counters / Dual Binary Up Counters

Description
The HD74HC4518 dual BCD counter and the HD74HC4520 dual binary counter consist of two identical, independent, internally synchronous 4-stage counters. The counter stages are type D flip-flops, with interchangeable Clock and Enable lines for incrementing on either the positive-goingor negative-going transition as required when cascading multiple stages. Each counter can be cleared by applying a high level on the Reset line. In addition, the HD74HC4518 will count out of all undefined states within two clock periods. These complementary MOS up counters find primary use in multi-stage synchronous or ripple counting applications requiring low power dissipation and/or high noise immunity.

Features
•  High Speed Operation
•  High Output Current: Fanout of 10 LSTTL Loads
•  Wide Operating Voltage: VCC= 2 to 6 V
•  Low Input Current: 1 µA max
•  Low Quiescent Supply Current: ICC(static) = 4 µA max (Ta = 25°C)

TC74HC4520AF DUAL 4-BIT BINARY COUNTER

The TC74HC4520A is high speed CMOS DUAL BCD/4-BIT BINARY COUNTER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Since it contains two independent counter circuits in one package, counting or frequency division of eight binary bits can be achieved with one device. The counter is reset to “O” (Q0 to Q3 low) by setting the CLR input high regardless of the other inputs. Counting occurs on the positive going (rising edge) transition of CK if CE is high or the negative going (falling edge) transition of CK if CE is low.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features
•  High speed: fmax =55 MHz (typ.) at VCC =5 V
•  Low power dissipation: ICC =4 μA (max) at Ta =25°C
•  High noise immunity: VNIH =VNIL =28% VCC(min)
•  Outputs drive capability: 10 LSTTL loads
•  Symmetrical output impedance: |IOH| =IOL =4 mA (min)
•  Balanced propagation delays: tpLH∼  − tpHL
•  Wide operating voltage range: VCC (opr) =2 to 6 V
•  Pin and function compatible with TC4520B

HCC4520BK Rad-hard high voltage CMOS logic series

Rad-hard high voltage CMOS logic series

Description
The HCC40xxx and HCC45xxx series are composed of over 70 types of high voltage CMOS
functions, offering a set of highly noise tolerant gates, Flip-Flops, multiplexers, counters, bus
interfaces and several other functions. The radiation hardness, the single event latch-up
(SEL) and the single event upset (SEU) immunity and the housing in hermetic packages of all types
of both series make them usable in the most difficult environmental conditions.

Features
■ 3 to 20 V max operating voltage
■ Bufferized inputs and outputs
■ Standardized symmetrical outputs characteristic
■ 50 ns typical propagation delays
■ 100 nA max 25 °C input current
■ 100% tested 20 V quiescent current
■ 5-10-15 V parametric testing
■ Hermetic packages
■ Rad-hard 100 kRad TID at 11rad/sec dose rate
■ SEL-SEU immune to 72 MeV/cm²/mg LET ions
■ ESCC qualified

74HC4520PW Dual 4-bit synchronous binary counter

GENERAL DESCRIPTION
The 74HC/HCT4520 are high-speed Si-gate CMOS devices and are pin compatible with the “4520” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT4520 are dual 4-bit internally synchronous binary counters with an active HIGH clock input (nCP0) and an active LOW clock input (nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an active HIGH overriding asynchronous master reset input (nMR).
The counter advances on either the LOW-to-HIGH transition of nCP0 if nCP1 is HIGH or the HIGH-to-LOW transition of nCP1 if nCP0 is LOW. Either nCP0 or nCP1 may be used as the clock input to the counter and the other clock input may be used as a clock enable input. A HIGH on nMR resets the counter (nQ0 to nQ3 = LOW) independent of nCP0 and nCP1.

FEATURES
• Output capability: standard
• ICC category: MSI

APPLICATIONS
• Multistage synchronous counting
• Multistage asynchronous counting
• Frequency dividers
