Product details

Quad 2-input AND gate in a compact 14-TSSOP

The Texas Instruments SN74HCT08PW is a 74HCT-series quad 2-input AND gate. Four independent AND gates share the same 4.5 V to 5.5 V supply rail and a common ground. Each gate has TTL-compatible input thresholds: logic-low at 0.8 V, logic-high at 2 V. The 14-TSSOP body (0.173" wide, 4.40 mm) saves board space on mixed-voltage digital boards.

Industrial temperature range and active lifecycle

Rated -40 °C to 85 °C, the SN74HCT08PW suits outdoor telecom cabinets, factory-floor PLC I/O cards, and engine-bay control modules. TI lists the part as Active. ROHS3 compliant. Package ships in tubes.

Frequently asked questions

What is the propagation delay of SN74HCT08PW?

Maximum propagation delay is 22 ns at 5.5 V supply with a 50 pF load. This timing clears hold margins for most 5 V synchronous buses below 20 MHz.

What are the direct equivalents for SN74HCT08PW?

The SN74HC21N is a 74HC-series AND gate with two 4-input gates in a through-hole package — different input count and footprint. The SN74LV08ADR is a 74LV-series quad 2-input AND gate in surface-mount SOIC, operating at 2 V to 5.5 V with faster propagation (7.9 ns at 5 V) and higher output drive (12 mA), but its LV inputs are not TTL-compatible. Neither is a drop-in pin-for-pin replacement; for a dual-source, qualify the SN74HCT08PW against the exact PCB footprint and threshold requirements.
