74VCX16501
Low Voltage 18-Bit Universal Bus Transceivers with 3.6V
Tolerant Inputs and Outputs
General Description
The VCX16501 is an 18-bit universal bus transceiver which
combines 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. For A-to-B data flow, the
device operates in the transparent mode when LEAB is
HIGH. When LEAB is LOW, the A data is latched if CLKAB
is held at a HIGH or LOW logic level. If LEAB is LOW, the A
bus data is stored in the latch/flip-flop on the LOW-to-HIGH
transition of CLKAB. When OEAB is HIGH, the outputs are
active. When OEAB is LOW, the outputs are in a high-
impedance state.
Data flow for B to A is similar to that of A to B but uses
OEBA, LEBA, and CLKBA. The output enables are com-
plementary (OEAB is active HIGH and OEBA is active
LOW).
The VCX16501 is designed for low voltage (1.65V to 3.6V)

CC
applications with I/O capability up to 3.6V.
The VCX16501 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

Note 1:
To ensure the high-impedance state during power up or power
down, OEBA should be tied to V
CC
through a pull-up resistor and OEAB
should be tied to GND through a pull-down resistor; the minimum value of
the resistors is determined by the current-sourcing capability of the driver.
