STMicroelectronics M74HC08RM13TR

Overview

M74HC08RM13TR from STMicroelectronics is a high-speed CMOS quad 2-input AND gate in SO14 package, operating from 2 V to 6 V supply, with typical propagation delay of 7 ns at 6 V, ±4 mA output drive, and -55 °C to +125 °C temperature range-used in digital logic control, industrial sequencers, and automotive body-control modules.

For engineers reviewing the M74HC08RM13TR datasheet, M74HC08RM13TR pinout, M74HC08RM13TR application, or M74HC08RM13TR equivalent, key selection criteria include supply voltage range, output drive capability, propagation delay matching across gates, and automotive-grade thermal stability in noise-prone environments.

Technical Context

The M74HC08RM13TR implements four independent AND logic functions using silicon gate C2MOS technology, with buffered outputs ensuring symmetrical rise/fall times and balanced tPLH/tPHL delays. Each gate accepts TTL- and CMOS-compatible input levels and drives standard CMOS loads up to 50 pF.

All inputs feature integrated protection circuits for ESD (HBM: 2 kV, CDM: 1 kV) and transient overvoltage suppression. The device operates without latch-up under recommended conditions and maintains stable logic thresholds across its full -55 °C to +125 °C industrial/automotive temperature range.

FAQ

What is the maximum capacitive load the M74HC08RM13TR can drive reliably?

The device is characterized for CL = 50 pF in AC specifications, with guaranteed tPLH/tPHL performance up to that load. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot; for >100 pF loads, add series termination or buffer stages. Measured output transition time remains <19 ns (max.) at 50 pF and 6 V supply.

Does M74HC08RM13TR support mixed-voltage interfacing between 3.3 V and 5 V domains?

Yes-the input thresholds scale with VCC (VIH ≥ 3.15 V at 4.5 V, VIL ≤ 1.35 V), enabling reliable 3.3 V outputs to drive the device when VCC = 5 V. However, 5 V inputs must not exceed VCC + 0.5 V; use clamping diodes or level shifters if VCC = 3.3 V and 5 V signals are present.

Is the SO14 package of M74HC08RM13TR lead-free and RoHS compliant?

Yes-the SO14 package uses lead-free terminations and complies with RoHS Directive 2011/65/EU and ST's ECOPACK® environmental program. The device carries the "E" suffix in marking per ST's eco-design standards, and all plating meets JEDEC J-STD-609 Category 2a (SnAgCu matte tin).

Can M74HC08RM13TR be used in place of obsolete 74LS08 in existing designs?

Yes-pin- and function-compatible with 74LS08, but requires attention to VCC range (2–6 V vs. LS's 4.75–5.25 V) and input drive (CMOS inputs draw negligible current vs. LS's 0.4 mA). Replace pull-up resistors with direct connections and verify fan-out margins; no level-shifting needed for 5 V systems.
