8-bit D-type with tri-state bus drive
The SN74S374N3 is an 8-bit D-type flip-flop from TI's 74S Schottky family, featuring tri-state non-inverted outputs and positive-edge triggering. The 110 mA quiescent current is a signature of the 74S bipolar process — this part draws power continuously regardless of clock activity, so it is best suited to bus-interface or register-buffer roles where the data path is always live, not for power-gated or battery-operated designs.
Through-hole DIP for legacy and breadboard builds
Housed in a 20-pin DIP (0.300-inch / 7.62 mm body) with a PDIP supplier package, the SN74S374N3 mounts through-hole — the 100-mil pin pitch and 0.025-inch square posts are breadboard- and protoboard-friendly. Output high current is 6.5 mA per pin — enough to drive one or two LSTTL loads or a low-current LED directly, but not a 50-ohm backplane or a relay coil without a buffer. The tri-state outputs let multiple devices share a common data bus when the output-enable control is wired to a chip-select decoder.
