Low Voltage 16-Bit Registered Transceiver
with 3-STATE Outputs
General Description
The LVT16952 and LVTH16952 are 16-bit registered
flowing in both directions 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) V
TTL interface to a 5V environment.
The LVT16952 and LVTH16952 are fabricated with an
advanced BiCMOS technology to achieve high speed oper-
ation similar to 5V ABT while maintaining low power dissi-
pation.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
