FEA TURES

•Wide supply voltage range of 1.2 V to 3.6 V

•Complies with JEDEC standard no. 8-1A

•CMOS low power consumption

•MULTIBYTE

•Low inductance multiple V

and ground bounce

•Direct interface with TTL levels

•Bus hold on all data inputs eliminates the need for external pull-up

resistors to hold unused inputs

•Output drive capability 50Ω transmission lines @ 85°C

DESCRIPTION

The 74ALVCH16540 is a high-performance, low-power, low-voltage,
Si-gate CMOS device, superior to most advanced CMOS
compatible TTL families.

The 74ALVCH16540 is a 16-bit inverting buffer/line driver with
3-State outputs. The 3-State outputs are controlled by the output
enable inputs 1OE
to assume a high impedance OFF-state.

Active bus hold circuitry is provided to hold unused or floating data
inputs at a valid logic level. This feature eliminates the need for
external pull-up or pull-down resistors. The device can be used as
four 4-bit buffers, two 8-bit buffers or one 16-bit buffer.
