HD74ALVCH162830
1-bit to 2-bit Address Driver with 3-state Outputs
ADE-205-197 (Z)
Preliminary
1st. Edition
November 1997
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, 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. Active bus hold
circuitry is provided to hold unused or floating inputs at a valid logic level. All outputs, which are designed
to sink up to 12 mA, include equivalent 26 Ω resistors to reduce overshoot and undreshoot.
Features
• VCC = 2.3 V to 3.6 V
• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
• Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
• High output current ±12 mA (@VCC = 3.0 V)
• Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
• All outputs have equivalent 26 Ω series resistors, so no external resistors are required

Conditions
TVSOP
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.

All input pulses are supplied by generators having the following characteristics :
PRR ≤ 10 MHz, Zo = 50 Ω, t r ≤ 2.0 ns, tf ≤ 2.0 ns. (VCC = 2.5±0.2 V)
PRR ≤ 10 MHz, Zo = 50 Ω, t r ≤ 2.5 ns, tf ≤ 2.5 ns. (VCC = 2.7 V, 3.3±0.3 V)
Waveform – A is for an output with internal conditions such that the output is low except
when disabled by the output control.
Waveform – B is for an output with internal conditions such that the output is high except
when disabled by the output control.
The output are measured one at a time with one transition per measurement.
