Description : HEX INVERTING Logic Level DOWN CONVERTERHEX Logic Level DOWN CONVERTER

General Description
The MM74HC4049 and the MM74HC4050 utilize advanced silicon-gate CMOS technology, and have a modified input protection structure that enables these parts to be used as logic level translators which will convert high level logic to a low level logic while operating from the low logic supply. For example, 0–15V CMOS logic can be converted to 0–5V logic when using a 5V supply. The modified input protection has no diode connected to VCC, thus allow ing the input voltage to exceed the supply. The lower zener diode protects the input from both positive and negative static voltages. In addition each part can be used as a simple buffer or inverter without level translation. The MM74HC4049 is pin and functionally compatible to the CD4049BC and the MM74HC4050 is compatible to the CD4050BC.

Features
■ Typical propagation delay: 8 ns
■ Wide power supply range: 2V–6V
■ Low quiescent supply current: 20 µA maximum (74HC)
■ Fanout of 10 LS-TTL loads

Description : CMOS HEX Buffer/CONVERTER

CMOS HEX Buffer/CONVERTER
The CD4050BMS is an non-INVERTING HEX buffer and features logic level conversion using only one supply voltage (VCC). The input signal high level (VIH) can exceed the VCC supply voltage when this device is used for logic level conversions. This device is intended for use as CMOS to DTL/TTL
CONVERTERs and can drive directly two DTL/TTL loads. (VCC= 5V, VOL≤0.4V, and IOL≥3.3mA.
The CD4050BMS is designated as replacement for CD4010B. Because the CD4050BMS requires only one power supply, it is preferred over the CD4010B and should be used in place of the CD4010B in all inverter, current driver, or logic level conversion applications. In these applications the CD4050BMS is pin compatible with the CD4010B, and can be substituted for this device in existing as well as in new designs. Terminal No. 16 is not connected internally on the CD4050BMS, therefore, connection to this terminal is of no consequence to circuit operation. For applications not requiring high sink current or voltage conversion, the CD4069UB HEX Inverter is ecommended.
The CD4050BMS is supplied in these 16 lead outline pack ages:
Braze Seal DIP H4T
Frit Seal DIP H1E
Ceramic Flatpack H3X
