Philips Semiconductors Product specification

16-bit bus transceiver with direction pin; 5V tolerant
(3-State)

FEA TURES

•5 volt tolerant inputs/outputs for interfacing with 5V logic

•Wide supply voltage range of 1.2V to 3.6V

•Complies with JEDEC standard no. 8-1A

•CMOS low power consumption

•MULTIBYTE

TM

flow-through standard pin-out architecture

•Low inductance multiple power and ground pins for minimum

noise and ground bounce

•Direct interface with TTL levels

•High impedance when V

CC

= 0

•All data inputs have bus hold (74LVCH16245A only)

DESCRIPTION

The 74LVC(H)16245A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most advanced
CMOS compatible TTL families. Inputs can be driven from either

3.3V or 5V devices. In 3-State operation, outputs can handle 5V .
These features allow the use of these devices in a mixed 3.3V/5V
environment.

The 74LVC(H)16245A is a 16-bit transceiver featuring non-inverting
3-State bus compatible outputs in both send and receive directions.
The 74LVC(H)16245A features two output enable (nOE
easy cascading and two send/receive (nDIR) inputs for direction
control. nOE

controls the outputs so that the buses are effectively
isolated. This device can be used as two 8-bit transceivers or one
16-bit transceiver.

The 74LVCH16245A bus hold data inputs eliminates the need for
extreme pull up resistors to hold unused inputs.
