CD54HC299F3A

The CD54HC299F3A from RCA is a high-speed CMOS logic 8-bit universal shift register featuring 3-state outputs. This device supports four operating modes: shift left, shift right, load, and store, and can be cascaded for N-bit word lengths. It offers bus drive capability and three-state functionality suitable for bus-oriented applications.

Key electrical characteristics include a typical maximum operating frequency of 50MHz at 5V supply and 15pF load capacitance. The output current capabilities are ±5.2mA (IOL/IOH max), and the maximum supply current is 160µA. The device operates within a wide voltage range, with HC types supporting 2V to 6V and HCT types supporting 4.5V to 5.5V.

Designed for a broad operating temperature range from -55°C to 125°C, the CD54HC299F3A is suitable for demanding environments. It features buffered inputs and balanced propagation delay and transition times, offering significant power reduction compared to LSTTL logic. The component is available in a CDIP (J) package, typically mounted through-hole.

This shift register provides high noise immunity for HC types and direct LSTTL input logic compatibility for HCT types. Its versatile configuration and robust performance make it a reliable choice for various digital logic applications requiring data shifting and storage capabilities.
