Octal Schmitt Bus Transceiver

The TC74VHCV245 is an advanced high speed CMOS OCTAL

BUS TRANSCEIVER fabricated with silicon gate CMOS

technology.

It achieves the high speed operation similar to equivalent Bipolar

Schottky TTL while maintaining the CMOS low power

dissipation.

It is intended for two-way asynchronous communication between

data busses. The direction of data transmission is determined by

the level of the DIR input.

The enable input ( G ) can be used to disable the device so that the

busses are effectively isolated.

Input pin and bus terminal have hysteresis between the

positive-going and negative-going thresholds. Thus the

TC74VHCV245 is capable of squaring up transitions of slowly

changing input signals and provides an improved noise immunity.

Input protection and output circuit ensure that 0 to 5.5 V can be

supply voltage. These structure prevents device destruction due to

mismatched supply and input/output voltages such as battery

back up, etc.

Note: Output in off-state.

Features (Note)

• Available in TSSOP and VSSOP (US)

• Power-down protection provided on all inputs and outputs

• Pin and function compatible with the 74 series

(74AC/VHC/HC/F/ALS/LS etc.) 245 type

Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.

All floating (high impedance) bus pins must have their input levels fixed by means of pull-up or pull-down

resistors.
