Overview
The 74AHCT377D,112 is an octal D-type flip-flop with data enable and positive-edge trigger, manufactured by NXP USA Inc. It belongs to the AHCT logic family, ensuring compatibility with standard CMOS outputs while accepting TTL-compatible inputs. The device features a single circuit containing eight bits of storage. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 18 MHz. The component utilizes a 16-pin SO package (SOT-163) and functions reliably across an extended temperature range from -40 °C to +125 °C.
Feature Summary
- Octal D-type flip-flop architecture with data enable functionality
- Positive-edge triggering mechanism for synchronous data capture
- AHCT logic family providing TTL input compatibility with CMOS output levels
Applications
- Data bus interface applications requiring parallel storage
- Shift register configurations for serial-to-parallel conversion
- Register stages in digital control systems
Procurement Notes
Verify the specific ordering code suffix to confirm the exact packaging configuration, as variations may exist between tube and reel formats. Confirm that the procurement source provides official documentation or traceability records to ensure authenticity. Check for any recent product change notifications regarding pinout or electrical specifications before finalizing orders.
Selection Notes
Select this component when designing circuits that require interfacing between TTL-level control signals and CMOS-based memory structures. The AHCT series is appropriate for systems needing robust noise immunity combined with standard logic level translation. Ensure the design accounts for the specified operating temperature range and supply voltage constraints during board layout and power planning.
Part Context
This part is a member of the Nexperia (formerly NXP Standard Products) 74AHCT series, which bridges the gap between older TTL standards and modern CMOS technologies. The 74HCT377 variant serves as a functional equivalent within the broader HCT family, offering similar performance characteristics but potentially differing in specific switching speed or drive current parameters defined by the manufacturer's datasheet.
Replacement Considerations
Direct substitutes include the 74AHCT377PW,112, which offers identical logical functionality in a TSSOP-20 package. Other compatible options within the same family are the 74HC377DB,112 and the 74HCT377DB,118, though these belong to different logic families with distinct voltage and speed characteristics.
