74VCX162601

Low Voltage 18-Bit Universal Bus Transceivers

with 3.6V Tolerant Inputs and

Outputs and 26 Series Resistors in the B-Port Outputs

General Description

The VCX162601, 18-bit universal bus transceiver, com-

bines 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. The clock can be con-

trolled by the clock-enable (CLKENAB and CLKENBA)

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-to-

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. Output-enable OEAB is active-LOW. When OEAB

is HIGH, the outputs are in the HIGH-impedance state.

Data flow for B to A is similar to that of A to B but uses

OEBA, LEBA, CLKBA and CLKENBA.

The 74VCX162601 is designed for low voltage (1.4V to

3.6V) V

The VCX162601 is also designed with 26 series resistors

in the B-Port outputs. This design reduces line noise in

applications such as memory address drivers, clock driv-

ers, and bus transceivers/transmitters.
