STMicroelectronics M74HCT132TTR

The M74HCT132TTR from STMicroelectronics is a high-speed CMOS Quad 2-Input NAND Schmitt Trigger manufactured using silicon gate C2MOS technology. This integrated circuit is designed to operate with a power supply range of 4.5V to 5.5V, making it compatible with TTL (Transistor-Transistor Logic) levels while offering the benefits of CMOS technology such as low power consumption and high noise immunity.

The device features four independent NAND gates with Schmitt-trigger action at each input, which makes it ideal for transforming slowly changing input signals into sharply defined, jitter-free output signals, thus enhancing noise immunity and transforming an irregular input waveform into a square wave output.

With its hysteresis characteristics, the M74HCT132TTR is particularly suitable for applications requiring noise filtering, signal conditioning, or in the creation of highly stable square wave signals for timing, clock, and pulse generation circuits. It is widely used in a variety of digital applications such as wave and pulse shapers, astable multivibrators, monostable multivibrators, and logic circuitry that requires high noise immunity.

The M74HCT132TTR comes in a TSSOP14 package, which is a thin shrink small outline package with 14 leads. It is a surface-mount device, which makes it suitable for automated assembly processes and equipment, and it helps to save space on printed circuit boards.

Key specifications of the M74HCT132TTR include:

• Supply Voltage Range: 4.5V to 5.5V
• High Noise Immunity: VNIH = VNIL = 28% VCC (Min)
• Low Power Dissipation: ICC = 2 µA (Max) at TA = 25°C
