Key Features
- 8-bit positive-edge-triggered D flip-flop with clock enable (hold mode) allowing selective register updates, reducing unnecessary state changes in bus interface designs
- HC CMOS logic family with maximum operating frequency of 20 MHz and 50 pF load capacitance, suitable for standard digital register and latch applications
- 20-pin TSSOP (R-PDSO-G20) compact surface-mount package enabling efficient PCB routing in digital systems with space constraints
Applications
The CD74HC377PW is widely used as an 8-bit data register and bus interface latch in microprocessor and microcontroller systems, where clocked data storage with enable control is required. It is commonly found in address/data latching circuits, output port expanders, and pipeline registers in digital logic designs. The hold mode feature makes it especially useful in bus-oriented architectures where data must be conditionally updated without dedicated tri-state buffers.

Frequently Asked Questions
What is the CD74HC377PW and how many bits does it have?
The CD74HC377PW is an 8-bit D-type flip-flop IC from the HC CMOS logic family. It features positive-edge clock triggering and a clock enable (hold mode), allowing all 8 bits to be selectively updated on the rising clock edge, making it a versatile data register for bus interface applications.
What is the maximum operating frequency of the CD74HC377PW?
The CD74HC377PW can operate at a maximum frequency of 20 MHz (20,000,000 Hz) under nominal supply conditions. This makes it suitable for standard-speed digital logic applications, including address latching, pipeline registers, and output port control in 8-bit microprocessor-based systems.
What does the hold mode feature do on the CD74HC377PW?
The hold mode (clock enable) on the CD74HC377PW allows the register to retain its current output state even when the clock is toggling, by deasserting the enable input. This prevents unintended data updates and is particularly useful in bus-multiplexed designs where selective register loading is required without additional external gating logic.
What package is the CD74HC377PW available in?
The CD74HC377PW is packaged in a 20-pin R-PDSO-G20 TSSOP (Thin Shrink Small Outline Package). This compact surface-mount package with a 0.65 mm pitch is compatible with standard SMT assembly processes and is appropriate for high-density digital logic boards.
