20-bit Universal Bus Driver with 3-state Outputs
ADE-205-209 (Z)
Preliminary
1st. Edition
January 1998
Description
This 20-bit universal bus driver is designed for 2.3 V to 3.6 V VCC 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 low. When LE is high, the A data is latched if the
clock (CLK) input is held at a high or low logic level. If 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 resistor; the minimum value of the resistor is determined by the current sinking capability of the
driver.
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 ±24 mA (@VCC = 3.0 V)

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.
