74LVTH16952
Low Voltage 16-Bit Registered Transceiver
with 3-STATE Outputs
General Description
The LVTH16952 is a 16-bit registered transceiver. Two 8-
bit back to back registers store data flowing in both direc-
tions between two bidirectional buses. Separate clock,
clock enable, and output enable signals are provided for
each register.
The LVTH16952 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
The registered transceiver is designed for low-voltage
(3.3V) VCC applications, but with the capability to provide a
TTL interface to a 5V environment.
The LVTH16952 is fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
Features
s Input and output interface capability to systems at
5V VCC
s Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink 32 mA/+64 mA
s Functionally compatible with the 74 series 16952
s Latch-up performance exceeds 500 mA
