CD54HC194F3A

The CD54HC194F3A from Texas Instruments is a high-speed CMOS logic integrated circuit featuring a 4-bit bidirectional universal shift register. This device supports four operating modes: Shift Right, Shift Left, Hold, and Reset, enabling versatile data manipulation.

With synchronous parallel or serial operation, the CD54HC194F3A achieves a typical maximum clock frequency of 60MHz at VCC = 5V and a load capacitance of 15pF at 25°C. It includes an asynchronous master reset function for immediate state control. The device offers standard outputs with a fanout of 10 LSTTL loads and bus driver outputs with a fanout of 15 LSTTL loads.

Designed for a wide operating temperature range of -55°C to 125°C, this shift register is suitable for various environmental conditions. It operates with HC types from 2V to 6V, providing high noise immunity with NIL and NIH at 30% of VCC. HCT types operate from 4.5V to 5.5V and offer direct LSTTL input logic compatibility. The CD54HC194F3A is packaged in a 16-pin CDIP (J) package, with a standard package quantity of 25 units in a tube.

This component is ideal for applications requiring efficient data shifting, storage, and manipulation within digital systems. Its balanced propagation delay and transition times, along with significant power reduction compared to LSTTL logic ICs, make it a robust choice for many designs.
