The HD74HC132 is a high-speed silicon-gate CMOS device containing four 2-input NAND Schmitt triggers. This device is useful in wave shaping, pulse squaring and any application requiring a comparator with hysteresis. Due to the Schmitt trigger action, the HD74HC132 exhibits different input threshold levels for positive-going (VT+) and negative-going (VT-) signals.

Applications:

• Wave shaping
• Pulse squaring
• Comparator circuits with hysteresis
• Noise suppression
• Clock generation

Features:

• High Speed Operation: tpd = 11 ns typ (VCC = 5 V)
• High Output Drive: Fanout of 10 LSTTL Loads
• Wide Operating Voltage: VCC = 2V to 6V
• Low Input Current: 1 μA max
• Low Quiescent Supply Current: ICC (static) = 1 μA max (Ta = 25°C)
• TTL Input Compatible

Benefits:

• Provides clean and stable output signals even with noisy or slowly changing input signals.
• Suitable for applications where noise immunity is crucial.
• Simplifies circuit design by combining a NAND gate with Schmitt trigger functionality.
• Offers a wide operating voltage range, providing flexibility in various applications.

Additional Details:

The HD74HC132 is supplied in a standard 14-pin DIP package. The input hysteresis is typically 0.8V at VCC = 5V. The device operates over a temperature range of -40°C to +85°C.
