74LCX16646
Low Voltage 16-Bit Transceiver/Register with 5V Tolerant
Inputs and Outputs
General Description
The LCX16646 contains sixteen non-inverting bidirectional
registered bus transceivers with 3-STATE outputs, provid-
ing multiplexed transmission of data directly from the input
bus or from the internal storage registers. Each byte has
separate control inputs which can be shorted together for
full 16-bit operation.The DIR inputs determine the direction
of data flow through the device. The CPAB and CPBA
inputs load data into the registers on the LOW-to-HIGH
transition (see Functional Description).
The LCX16646 is designed for low voltage (2.5V or 3.3V)

CC
applications with capability of interfacing to a 5V signal
environment.
The LCX16646 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
