The MM74HC08 is a Quad 2-Input AND Gate manufactured by Fairchild Semiconductor Corporation. It has a typical propagation delay of 7ns, a fanout of 10 LS-TTL loads and a maximum static power consumption of 2µA.
The MM74HC08 is a quad 2‑input AND gate built with advanced silicon‑gate CMOS technology, offering LS‑TTL‑compatible speeds with low CMOS power consumption. It features buffered outputs, a fan‑out of 10 LS‑TTL loads, and internal diode clamps that protect inputs from static discharge.
The datasheet lists typical propagation delays of 7 ns (low‑to‑high) and 12 ns (high‑to‑low), a quiescent power consumption of 2 µA, and a supply voltage range of 2 V to 6 V. It also details absolute maximum ratings, DC and AC electrical characteristics, and provides mechanical drawings for SOIC, SOP, TSSOP, and PDIP packages.
| Quiescent power consumption | 2 µA max at room temperature |
