HD74ALVC162834A
18-bit Universal Bus Driver with 3-state Outputs
and Inverted Latch Enable
ADE-205-293B (Z)
Rev. 2
Oct. 2001
Description
The HD74ALVC162834A is an 18-bit universal bus driver designed for 2.3 V to 3.6 V VCC 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) is low. When LE is low, the A data is latched if the clock (CLK) input is held
at a high or low logic level. If the LE is high, 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 VCC through a
pullup registor; the minimum value of the registor is determined by the current sinking capability of the
driver.
All outputs, which are designed to sink up to 12 mA, include series dumping resistors to reduce overshoot
and undershoot.

CC = 2.3 V to 3.6 V
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)
All outputs have series dumping resistors, so no external resistors are required
tpd (CLK to Y) = 3.5 ns (Max) (@VCC = 3.3±0.3 V, CL = 50 pF, Ta = 0 to 85°C)
tpd (CLK to Y) = 2.5 ns (Max) (@VCC = 3.3±0.3 V, CL = 30 pF, Ta = 0 to 85°C)

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 condition” is not implied. Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability.
Notes: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp
current ratings are observed.
2. The input and output positive-voltage ratings may be exceeded up to 4.6 V if the input and output
clamp-current ratings are observed.
3. The maximum power dissipation is calculated using a junction temperature of 150°C and board
trace length of 750 mils.

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