HD74ALVCH16835
18-bit Universal Bus Driver with 3-state Outputs
ADE-205-126D (Z)
5th. Edition
December 1999
Description
The HD74ALVCH16835 is an 18-bit universal bus driver designed for 2.3 V to 3.6 V V
CC
operation. Data
flow from A to Y is controlled by the output enable (
OE
). 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 the LE is low, the A bus 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, the output ebable (
OE
) input 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.
Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
Features
Supports unregulated battery operation down to 2.7 V
Bus hold on data inputs eliminates the need for external pullup resistors.
Distrlbuted V
CC
and GND pin conflguration minimizes high speed switching noise.
