STMicroelectronics M74HCT00RM13TR

Overview

M74HCT00RM13TR from STMicroelectronics is a high-speed CMOS quad 2-input NAND gate in TSSOP-14 package, featuring 12 ns typical propagation delay at 4.5 V, ±4 mA symmetrical output drive, TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and 1 µA max quiescent ICC at 25°C - used in digital logic interfacing between HCMOS, TTL, and NMOS systems.

For engineers reviewing the M74HCT00RM13TR datasheet, M74HCT00RM13TR pinout, M74HCT00RM13TR application, or M74HCT00RM13TR equivalent, key selection criteria include guaranteed 4.5–5.5 V operation, -55°C to +125°C industrial temperature range, balanced tPLH/tPHL delays, 40 pF power dissipation capacitance, and TSSOP-14 footprint compatibility with space-constrained PCB layouts.

Technical Context

The M74HCT00RM13TR implements four independent NAND gates using silicon gate C2MOS technology with three-stage buffered outputs, enabling high noise immunity and stable switching across voltage and temperature extremes. Its input protection circuits guard against ESD and transient overvoltage, while symmetrical output impedance ensures matched rise/fall times.

Designed for direct interfacing between HCMOS logic families and legacy TTL/NMOS components, it operates within strict DC input voltage limits (–0.5 V to VCC + 0.5 V) and supports 500 ns max input transition times without timing degradation under recommended conditions.

FAQ

Is M74HCT00RM13TR pin-compatible with standard 74-series 00 devices?

Yes - it is fully pin- and function-compatible with the 7400, 74LS00, and 74F00 families in TSSOP-14. All 14 pins match the industry-standard dual-in-line layout, including identical input/output assignments and GND/VCC positions. No PCB redesign is needed when upgrading from through-hole or SOIC variants.

What is the maximum input transition time supported without timing violation?

The device supports input rise/fall times up to 500 ns at VCC = 4.5–5.5 V without violating AC specifications. This is verified per AC electrical characteristics table on page 3 of the official datasheet, ensuring reliable operation even with slow-switching sensors or RC-filtered control lines.

Does M74HCT00RM13TR require external pull-up or pull-down resistors on unused inputs?

No - all inputs feature internal protection diodes and defined logic thresholds, but floating inputs are not recommended. For unused gates, tie both inputs to VCC or GND to prevent oscillation and minimize ICC. The datasheet explicitly advises against leaving inputs unconnected due to potential increased supply current and noise susceptibility.

Can M74HCT00RM13TR drive a 50 pF capacitive load at 10 MHz?

Yes - with CL = 50 pF and input tr/tf = 6 ns, the device achieves 12 ns typical tPD and 8–15 ns output transition time. At 10 MHz (100 ns period), timing margins remain sufficient; however, total capacitive load should stay ≤50 pF to maintain specified AC performance per test conditions on page 3.
