74LVTH16500

Low Voltage 18-Bit Universal Bus Transceivers

with 3-STATE Outputs (Preliminary)

General Description

The LVTH16500 is an 18-bit universal bus transceiver

combining D-type latches and D-type flip-flops to allow

data flow in transparent, latched, and clocked modes.

Data flow in each direction is controlled by output-enable

(OEAB and OEBA), latch-enable (LEAB and LEBA), and

clock (CLKAB and CLKBA) inputs.

The LVTH16500 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

applications, but with the capability to provide a TTL inter-

face to a 5V environment. The LVTH16500 is fabricated

with an advanced BiCMOS technology to achieve high

speed operation similar to 5V ABT while maintaining low

power dissipation.
