HD74AVC16834
18-bit Universal Bus Driver with 3-state Outputs
ADE-205-291 (Z)
Preliminary
1st. Edition
May 1999
Description
The HD74AVC16834 is a 18-bit universal bus driver is operational at 1.2 V to 3.6 V V
CC
, but designed spe-
cifically for 1.65 V to 3.6 V V
CC
operation.
Data flow from A to Y is controlled by the output enable (OE) input. The device operates in the transparent
mode when the latch enable (LE) input is high. The A data is latched if the clock (CLK) input is held at a high
or low logic level. If LE is low, the A data is stored in the latch/flip flop on the low to high transition of CLK.
When OE is high, the outputs are in the high impedance state.
To ensure the high impedance state during power up or power down, OE should be tied to V
CC
through a
pullup registor; the minimum value of the registor is determined by the current sinking capability of the driv-
er.
Features
