The CD74HC299E is an 8-bit universal shift register manufactured by Texas Instruments, designed for bus-oriented applications with its three-state outputs. This device offers four synchronous operating modes: shift left, shift right, load, and store, controlled by select inputs.
Key electrical characteristics include a typical maximum clock frequency of 50MHz at 5V and 15pF load. It supports a wide operating voltage range, with HC types operating from 2V to 6V and HCT types from 4.5V to 5.5V. The device exhibits high noise immunity, with NIL and NIH at 30% of VCC at 5V. Standard outputs provide a fanout of 10 LSTTL loads, while bus driver outputs offer a fanout of 15 LSTTL loads.
The CD74HC299E is housed in a 20-pin PDIP package and operates within a temperature range of -55°C to 125°C. It can be cascaded to create longer word lengths. The master reset is an asynchronous active-low input.
This shift register is suitable for various digital logic applications requiring data manipulation and transfer, particularly in systems where bus interfacing is necessary.
