Device Structure

The CY74FCT273TQCT contains a single flip-flop element that is organized as 8 D-type latches. It is triggered by the positive edge of the clock signal and includes an asynchronous master reset. All eight flip-flops are controlled by a single clock and reset input. The integrated circuit is housed in a small-outline, surface mount SSOP package with 20 pins to facilitate compact PCB design.

Performance Characteristics

Fast signal processing due to low propagation delay (13ns)

High drive output capability (32mA/64mA) supports direct drive of large loads

Low power consumption, with low quiescent current (200µA)

Stable over a wide operating temperature range (-40°C to +85°C)

Reliable digital data storage and edge-triggered operation reduces timing errors

Application Environments

Used in bus data storage, memory interface, and timing circuits

Suitable for microprocessor systems, FPGA and ASIC-based designs

Common in communication equipment, industrial controls, computing hardware, data acquisition, and peripheral devices

Selection Guidelines

Choose CY74FCT273TQCT for applications needing:

8-bit D-type logic flip-flop with a master reset

High-speed and high-drive output requirements

Operation in industrial temperature ranges

Surface mounting in compact electronic designs

Check for compatibility with 4.75V~5.25V power supplies and ensure the output current matches your load.
