The SN74AS195N features a direct overriding clear (CLR) input, which can be used to clear the register to a low level without regard for the clock or other input conditions. The clock (CLK) input controls the serial data entry, and the register provides parallel data inputs (A, B, C, D) for 4-bit wide access. It also includes a serial output (Q0') for cascading purposes, which allows multiple devices to be connected in series to achieve longer shift register chains.

With its high-speed Advanced Schottky (AS) logic technology, the SN74AS195N provides fast switching speeds, making it an excellent choice for high-speed data manipulation tasks. The complementary outputs offer flexibility in interfacing with other logic families and driving various loads.

Applications for the SN74AS195N include serial-to-parallel data conversion, data storage, shift-left or shift-right operations, and pattern generation. Its robust design ensures reliable operation in commercial-grade environments, and the through-hole PDIP-16 package allows for easy implementation on printed circuit boards.

Texas Instruments' commitment to quality and performance is evident in the SN74AS195N, making it a go-to choice for designers who require a dependable and efficient 4-bit parallel-access shift register.
