The 74VCX16601 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 of the 74VCX16601 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 controlled 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. When OEAB is LOW, the outputs are active. 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 74VCX16601 is designed for low voltage (1.4V to 3.6V) V_CC applications with I/O capability up to 3.6V.

The 74VCX16601 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
