HD74ALVCH16830
1-bit to 2-bit Address Driver with 3-state Outputs
ADE-205-196 (Z)
1st. Edition
February 2000
Description
This 1-bit to 2-bit address driver is designed for 2.3 V to 3.6 V V
CC
operation. 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 inputs at a valid logic level.

Notes:
Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage
to the device. These are stress ratings only, and functional operation of the device at these or
any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute maximum rated conditions for extended periods may affect device
reliability.
1. The input and output negative voltage ratings may be exceeded if the input and output clamp
current ratings are observed.
2. This value is limited to 4.6 V maximum.
3. The maximum package power dissipation is calculated using a junction temperature of 150
°
C
and a board trace length of 750 mils.
