Octal D-type register for 5V bus applications
The SN74AS374N is an octal D-type flip-flop from Texas Instruments' 74AS family, packing eight edge-triggered registers into a single 20-pin DIP. It captures data on the rising edge of the clock and presents it at tri-state outputs, which means a shared data bus can be driven by multiple devices without contention — the outputs go high-impedance when the output-enable control is asserted. Rated for a 125 MHz clock frequency with a 9 ns propagation delay into a 50 pF load at 5 V, this part handles moderate-speed parallel buses in 5 V logic systems. The 4.5 V to 5.5 V supply range keeps it compatible with standard TTL and 5 V CMOS rails.
Through-hole DIP for prototyping and legacy boards
Housed in a 20-DIP (0.300-inch, 7.62 mm) through-hole package, the SN74AS374N is a natural fit for breadboard prototyping, socketed designs, or retrofitting older boards where surface-mount rework is impractical. The 20-PDIP supplier package mates with standard DIP sockets or can be soldered directly into plated through-holes. Operating temperature is specified for 0°C to 70°C ambient — the commercial grade covers indoor equipment, test gear, and benchtop instruments. The 120 mA quiescent current is typical for the 74AS family's higher-speed bipolar logic; budget the supply accordingly in a mixed-voltage design.
