What are the key features of SN74F174ANS?
- 6 independent D-type flip-flops sharing a single clock for synchronous parallel operation
- FAST (F) logic family with propagation delay below 5 ns
- Asynchronous active-low master reset clears all 6 flip-flops simultaneously
- 5 V supply voltage compatible with TTL and LS-TTL logic families
- 16-pin DIP package for through-hole prototyping and legacy board designs
- High output drive for bus and fanout-sensitive register applications
What is SN74F174ANS used for?
SN74F174ANS is commonly used in microprocessor-based systems and programmable logic designs that need high-speed 6-bit data registers for address latching, pipeline stages, or I/O port buffering. It is well suited for FPGA prototyping boards and legacy TTL-based industrial controllers where through-hole DIP placement is preferred. The shared clock and reset architecture also makes it a reliable choice for data synchronization stages in communication interface circuits running at 5 V.

Frequently Asked Questions
How fast is the SN74F174ANS, and which logic families can it interface with?
SN74F174ANS belongs to the FAST (F) logic family and achieves a typical clock-to-output propagation delay of approximately 4.5 ns at 5 V, making it considerably faster than LS-TTL parts. Its input and output voltage thresholds are compatible with standard 5 V TTL, LS-TTL, and CMOS families, so it can drive and receive signals on mixed-logic boards without level-translation circuits.
For a 6-bit address latch in a legacy 8-bit microprocessor board, how should SN74F174ANS be wired?
Connect the 6 D inputs to the six address or data lines to be latched, tie the shared CLK line to the system address-valid strobe, and use the active-low MR (master reset) pin to initialize the register during power-up. The common clock ensures all 6 bits update simultaneously within 5 ns of the rising clock edge, preventing bit skew across the 16-pin DIP footprint and meeting setup and hold time requirements of typical 5 V bus interfaces.
Does SN74F174ANS have individual resets or only a shared master reset?
SN74F174ANS provides only a single active-low asynchronous master reset that simultaneously clears all 6 flip-flop outputs to logic low regardless of the clock state. There are no individual per-bit reset inputs. If per-bit asynchronous clear is required, designers should consider the SN74F174 variant with separate CLR lines or use external gating on the 5 V supply rail to selectively reset individual bits before the clock edge.
What are the package dimensions and pin pitch of the 16-pin DIP used for SN74F174ANS?
The 16-pin DIP (dual in-line package) used for SN74F174ANS has a 2.54 mm (100 mil) pin pitch, a row spacing of 7.62 mm (300 mil), and a total body length of approximately 19.3 mm. These standard through-hole dimensions are fully compatible with breadboards, IC sockets, and legacy PCBs designed for 16-pin 300-mil DIP footprints, making it easy to replace older SN74F174 DIP devices without any mechanical rework.
