SN74LS166AN Description

Short technical summary and product information.

The SN74LS166AN is an 8-bit shift register IC manufactured by Texas Instruments. This device features parallel-in and serial-out capabilities, making it suitable for data conversion and serial transmission applications.

 

Key electrical specifications include a maximum clock frequency of 25 MHz and a supply voltage range of 4.75V to 5.25V. The operating temperature range is from 0°C to 70°C. The output type is Push-Pull, with a maximum IOL of 8 mA and a maximum IOH of -0.4 mA. The technology family is LS (Low-power Schottky).

 

This shift register is designed for through-hole mounting and comes in a 16-PDIP package. It is compatible with most other TTL logic families. The device features gated clock inputs and an overriding clear input for flexible control. Input clamping diodes minimize switching transients, simplifying system design.
