74LVTH16501
Low Voltage 18-Bit Universal Bus Transceivers
with Bushold and 3-STATE Outputs
General Description
The LVTH16501 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 LVTH16501 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
applications, but with the capability to provide a TTL inter-
face to a 5V environment. The LVTH16501 is fabricated
with an advanced BiCMOS technology to achieve high
speed operation similar to 5V ABT while maintaining low
power dissipation.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
