CD74HCT299M

The CD74HCT299M from Texas Instruments is an 8-bit universal shift register designed for high-speed CMOS logic applications. This device features TTL-compatible CMOS inputs and 3-state outputs, making it suitable for bus-oriented systems.

Key electrical specifications include a clock frequency of 24 MHz, an IOL max of 4 mA, and an IOH max of -4 mA. The device operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 160 µA. It is designed with buffered inputs and supports four operating modes: Shift Left, Shift Right, Load, and Store.

This shift register can be cascaded to achieve longer word lengths. It is housed in a 20-SOIC package and is designed for surface mounting. The operating temperature range is -55°C to 125°C, ensuring reliable performance in various environmental conditions.

Features such as balanced outputs, high speed, and positive input clamp diodes contribute to its robust performance. The HCT technology ensures direct LSTTL input logic compatibility.
