The 74LS32 is a quad 2-input OR gate integrated circuit (IC) that belongs to the 74xx series of digital logic ICs. The 74LSxx series is known for its high-speed operation and compatibility with other TTL (transistor-transistor logic) devices. The 74LS32 specifically contains four separate OR gates, each of which has two input terminals and one output terminal.
- Supply Voltage (VCC): Typically 5V (4.75V – 5.25V range).
- Input Voltage (VIH / VIL): High: ~2V, Low: ~0.8V.
- Output Voltage (VOH / VOL): High: ~2.7V, Low: ~0.5V.
- Propagation Delay: Around 9 ns (low-to-high and high-to-low transitions).
- Temperature Range: 0°C to 70°C.
- Power Dissipation (PD): Max 500 mW.
- Package: 14-pin DIP.
- Logic Compatibility: Compatible with TTL and 5V CMOS.
- Function: Four independent OR gates, each with 2 inputs, 1 output.
- Hysteresis: Schmitt-trigger inputs for noise immunity.
