Description : Octal Buffer/Line Driver with TRI-STATE® Outputs

General Description
The ’FCT244 is an octal buffer and Line Driver with TRI-STATE outputs designed to be employed as a memory and address Driver, clock Driver, or bus-oriented transmitter/receiver.

Features
■ Non-inverting buffers
■ Output sink capability of 48 mA, source capability of 12 mA
TRI-STATE outputs drive Lines or buffer memory address registers
■ TTL input and output level compatible
■ CMOS power consumption
■ Standard Microcircuit Drawing (SMD) 5962-8763001

Description : CMOS quad TRI-STATE differential Line Driver

Description
The ST26C31 is a quad differential Line Driver designed for digital data transmission over balanced Lines and meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The ST26C31 accepts TTL or CMOS input levels and translates these to RS-422 output levels. This part uses special outputs circuitry common to all four Drivers. All outputs are protected against damage due to electrostatic discharge by diode to VCC and ground.

General features
■ TTL input compatible
■ Typical propagation delay: 6ns
■ Typical output skew: 0.5ns
■ Output will not load Line when VCC = 0V
■ Meets the requirements of EIA standard RS-422
■ Operation from single 5V supply
■ 3-state outputs for connection to system buses
■ Low quiescent current
■ Available in surface mount

Description : Quad Single-Ended Line DriverDual Differential Line Driver

General Description
The MM88C30 is a Dual differential Line Driver that also performs the Dual four-input NAND or Dual four-input AND function. The absence of a clamp diode to VCC in the input protection circuitry of the MM88C30 allows a CMOS user to interface systems operating at different voltage levels. Thus, a CMOS digital signal source can operate at a VCC voltage greater than the VCC voltage of the MM88C30 Line Driver. The differential output of the MM88C30 eliminates ground-loop errors.
The MM88C29 is a non-inverting single-wire transmission Line Driver. Since the output ON resistance is a low 20Ω typ., the device can be used to drive lamps, relays, solenoids, and clock Lines, besides driving data Lines.

Features
■ Wide supply voltage range: 3V to 15V
■ High noise immunity: 0.45 VCC (typ.)
■ Low output ON resistance: 20Ω (typ.)

Description : Dual 4-Line-to-1-Line Data Selectors / Multiplexers (with three-state outputs)

Dual 4-Line-to-1-Line Data Selectors / Multiplexers (with three-state outputs)

This data selector / multiplexer contains inverters and Drivers to supply fully complementary, on-ship, binary decoding data selection to AND-OR gates.
Separate output control inputs are provided for each of the two four-Line sections. The three-state outputs can interface with and drive data Lines of bus-organized systems. With all but one of the common outputs disabled (at high-impedance state) the low-impedance of the single enabled output will drive the bus Line to a high or low logic level.
