DESCRIPTION

The LCX244 is a low voltage CMOS OCTAL BUS

BUFFER (NON-INVERTED) fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology. It is ideal for low

power and high speed 3.3V applications; it can

be interfaced to 5V signal environment for both

(TSSOPPackage)

inputsandoutputs.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

This device is designed to be used with 3 state

memoryaddressdrivers, etc.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

2. 74VHC244

74VHC244

Octal Buffer/Line Driver with 3-STATE Outputs

General Description

The VHC244 is an advanced high speed CMOS octal bus

buffer fabricated with silicon gate CMOS technology. It

achieves high speed operation similar to equivalent Bipolar

Schottky TTL while maintaining the CMOS low power dissi-

pation. The VHC244 is a non-inverting 3-STATE buffer hav-

ing two active-LOW output enables. These devices are

designed to be used as 3-STATE memory address drivers,

clock drivers, and bus oriented transmitter/receivers.

An input protection circuit ensures that 0V to 7V can be

applied to the input pins without regard to the supply volt-

age. This device can be used to interface 5V to 3V systems

and two supply systems such as battery back up. This cir-

cuit prevents device destruction due to mismatched supply

and input voltages.

Features

■High Speed: tPD =3.9ns (typ) at VCC =5V

■High noise immunity: VNIH =VNIL =28% VCC (min)

■Power down protection is provided on all inputs

■Low noise: VOLP =0.6V (typ)

■Low power dissipation: ICC =4 mA (max) @ TA=25°C

■Pin and function compatible with 74HC244

Ordering Code:

Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter ìXî to the ordering code.

74VHCT244A

Octal Buffer/Line Driver with 3-STATE Outputs

General Description

The VHCT244A is an advanced high speed CMOS octal

bus transceiver fabricated with silicon gate CMOS technol-

ogy. It achieves high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low

power dissipation. The VHCT244A is a non-inverting 3-

STATE buffer having two active-LOW output enables. This

device is designed to be used as 3-STATE memory

address drivers, clock drivers, and bus oriented transmitter/

receivers.

Protection circuits ensure that 0V to 7V can be applied to

the input and output (Note 1) pins without regard to the

supply voltage. These circuits prevent device destruction

due to mismatched supply and input/output voltages. This

device can be used to interface 5V to 3V systems and two

supply systems such as battery back up.

Note 1: Outputs in OFF-State

Features

■High Speed: tPD =5.9 ns (typ) at VCC =5V

■Power down protection is provided on inputs and

outputs

■Low power dissipation: ICC =4 mA (max) @ TA=25°C

■Pin and function compatible with 74HCT244
