This 18-bit universal bus transceiver is designed
for 1.65-V to 3.6-V VCC operation.
The SN74ALVCHR16601 combines D-type latches and D-type flip-flops to allow data flow in transparent,
latched, clocked, and clock-enabled 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 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 or low logic level. If LEAB is low, the A 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 outputs include equivalent 26-Ω series resistors to reduce overshoot and undershoot.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
