20-bit registered driver with inverted register enable and
30 Ω termination resistors; 3-state
Product data sheet

General description
The 74ALVC162836A is a 20-bit universal bus driver. Data flow is controlled by output
enable (OE), latch enable (LE) and clock inputs (CP).
When LE is HIGH, the An to Yn data flow is transparent. When LE is HIGH and CP is
held at LOW or HIGH, the data is latched; on the LOW to HIGH transient of CP the A-
data is stored in the latch/flip-flop.
The 74ALVC162836A is designed with 30 Ω series resistors in both HIGH or LOW output
stages.
When OE is LOW the outputs are active. When OE is HIGH, the outputs go to the
high impedance OFF-state. Operation of the OE input does not affect the state of the
latch/flip-flop.
To ensure the high-impedance state during power up or power down, OE should be tied
to V
CC
through a pullup resistor; the minimum value of the resistor is determined by the
current-sinking capability of the driver.
