HD74ALVCHS162830 - 1-bit to 2-bit Address Driver with 3-state Outputs

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.

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.
  • Diode on inputs clamp overshoot HD74ALVCHS162830 Function Table Inputs OE1.

HD74ALVCHS162830 1-bit to 2-bit Address Driver with 3-state Outputs ADE-205-221 (Z) Preliminary 1st. Edition July 1998 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. Diodes to VCC have been added on the inputs to clamp overshoot. Features • VCC = 2.3 V to 3.6 V • Typical VOL ground bounce < 0.8 V (@VCC = 3.
