HD74ALVCH162825 Overview
The HD74ALVCH162825 can be used as two 9-bit buffers or one 18-bit buffer. The 3-state control gate is a 2-input AND gate with active low inputs so that if either output enable ( OE1 or OE2) input is high, all nine affected outputs are in the high impedance state. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
HD74ALVCH162825 Key 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
