74LCX32652
Low Voltage Transceiver/Register
with 5V Tolerant Inputs and Outputs (Preliminary)
General Description
The LCX32652 contains thirty-two non-inverting bidirec-
tional bus transceivers with 3-STATE outputs providing
multiplexed transmission of data directly from the input bus
or from the internal registers. Data on the A or B bus will be
clocked into the registers as the appropriate clock pin goes
to the HIGH logic level. Each byte has separate control
inputs which can be shorted together for full 32-bit opera-
tion. Output Enable pins (OEAB_n, OEBA_n) are provided to
control the transceiver function (see Functional Descrip-
tion).
The LCX32652 is designed for low-voltage (2.5V or 3.3V)
V_CC applications with capability of interfacing to a 5V signal
environment.
The LCX32652 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

(Preliminary)
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to V_CC and OE tied to GND through a resistor: the minimum
value or the resistor is determined by the current-sourcing capability of the
driver.
