STMicroelectronics 74VHCT03AMTR: A Robust Quad 2-Input NAND Gate with Open Drain

The 74VHCT03AMTR is a high-speed Si-gate CMOS device from STMicroelectronics that belongs to the VHCT family. This product is designed to interface TTL to 5V CMOS. It is fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

The 74VHCT03AMTR is a quad 2-input NAND gate with open-drain outputs. This configuration allows for the realization of several logic functions. Open-drain outputs create the possibility of external pull-up resistors, making this component ideal for wired-AND logic functions that can operate with higher voltage levels than the device's supply voltage.

This device is guaranteed to operate over the full voltage range of 4.5V to 5.5V, with inputs and outputs that are high noise immunity. The 74VHCT03AMTR is characterized for operation from -40°C to +125°C, making it suitable for industrial applications where temperature resilience is essential.

Key features include the following:

• High-Speed: Typical t<sub>PD of 8ns at V<sub>CC = 5V, C<sub>L = 50pF.
• Low Power Dissipation: I<sub>CC is 2μA maximum at TA = 25°C.
• High Noise Immunity: V<sub>NIH and V<sub>NIL of 28% V<sub>CC minimum.
• Power Down Protection: Inputs and outputs on all pins can withstand ≤ 0.5V to 7V, regardless of the supply voltage.
• Pin and Function Compatible with Other Standard Logic Families: LSTTL, ALVC, ALVT, LVC, LV, LV-A, and LCX where applicable.

The 74VHCT03AMTR is provided in a SO-14 package, which is a small outline package that is widely used and suitable for automated assembly processes. This device is also available in TSSOP14 and DIP14 packages. The product is delivered on tape and reel, ensuring it is ready for use in high-volume manufacturing environments.

With its combination of high speed, robustness, and compatibility, the 74VHCT03AMTR from STMicroelectronics is an excellent choice for designers who require reliable logic gates that can bridge different logic standards and operate in demanding conditions.
