Key Features
- Octal 3-state D flip-flop with 90MHz maximum operating frequency enables high-speed data latching and bus interfacing in fast digital systems
- ACT-family TTL-compatible inputs with CMOS outputs bridge TTL and CMOS logic families, simplifying mixed-logic system design without level-shift circuitry
- Active-low output enable control allows multiple devices to share a common bus without contention, ideal for data bus expansion and memory interface designs
Applications
The SN74ACT374PWRG4 is commonly used as a data bus register and output latch in microprocessor systems, FPGA I/O expansion, and memory address demultiplexing circuits. Its 3-state outputs and 90MHz speed make it ideal for high-speed data pipeline stages, address latches, and parallel-to-serial data conversion in communications equipment. The ACT-family TTL-compatible inputs allow direct interfacing with legacy TTL logic while driving CMOS loads in mixed-technology board designs.

Frequently Asked Questions
What is the maximum operating frequency of the SN74ACT374PWRG4?
The SN74ACT374PWRG4 supports a maximum operating frequency of 90MHz at nominal supply voltage, making it suitable for high-speed data latching and bus interface applications in fast microprocessor systems and digital signal processing pipelines.
What does the 3-state output feature mean for the SN74ACT374PWRG4?
The 3-state (tri-state) outputs of the SN74ACT374PWRG4 allow the device outputs to be placed in a high-impedance state via the active-low output enable pin. This enables multiple devices to share a common data bus without signal contention, which is essential for bus-oriented system architectures.
What package does the SN74ACT374PWRG4 come in?
The SN74ACT374PWRG4 is available in a 20-pin TSSOP (Thin Shrink Small Outline Package), designated R-PDSO-G20 per JESD-30. The compact TSSOP package with 0.65mm pitch is well-suited for space-constrained PCB designs in portable and high-density digital systems.
What logic family does the SN74ACT374PWRG4 belong to?
The SN74ACT374PWRG4 belongs to the ACT (Advanced CMOS with TTL-compatible inputs) logic family, which accepts standard TTL input thresholds while providing full CMOS output swing. This makes it ideal for interfacing between TTL and CMOS logic in mixed-technology digital systems.
