The 74F195A is a 4-Bit Parallel Access Shift Register produced by Philips Semiconductors. It has shift right and parallel load capabilities, J-K (D) inputs to the first stage, complement output from the last stage, and asynchronous master reset. This device is useful in a variety of shifting, counting, and storage applications. It performs serial, parallel, serial to parallel, or parallel to serial data transfers at very high speeds.
This document is a product specification datasheet for the Philips 74F195A, a 4-bit parallel-access shift register designed for high-speed data transfer applications. The device supports both shift right and parallel load modes, controlled by the Parallel Enable (PE) input, and includes features such as J-K type serial inputs and an asynchronous Master Reset.
| Supply voltage | 4.5V to 5.5V |
|---|---|
| Operating temperature range | 0°C to +70°C |
| Package type | 16-pin plastic DIP |
| Number of bits | 4-bit |
A Low signal on the asynchronous Master Reset (MR) input sets all Q outputs Low, independent of any other input condition.
The maximum clock frequency reaches up to 180 MHz in load mode and 190 MHz in shift mode.
The device operates within a free-air temperature range of 0 to +70 °C.
