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.
The transceiver is designed for low voltage (3.3V) V_CC
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.
