Texas Instruments SN74HC595N 8-Bit Shift Register, DIP-16

The Texas Instruments SN74HC595N is a high-performance, 8-bit shift register featuring a 3-state output register. This integrated circuit incorporates an 8-bit serial-in, parallel-out shift register that directly feeds an 8-bit D-type storage register, providing efficient data handling and output control. The storage register boasts parallel 3-state outputs, allowing multiple devices to be connected to a common bus without interference.

Separate clock inputs are provided for both the shift and storage registers, offering precise timing control. The shift register includes a direct overriding clear (SRCLR) input, a serial (SER) input for data, and serial outputs for easy cascading of multiple devices. When the output-enable (OE) input is held high, all outputs enter a high-impedance state, which is essential for bus-oriented applications.

Engineered for reliability across a broad spectrum of uses, this shift register is suitable for demanding applications such as network switches, power infrastructure, LED display drivers, and server systems. Its robust design ensures stable operation in complex digital environments.

Key technical advantages include a wide operating voltage range from 2V to 6V, making it versatile for various logic levels. The high-current 3-state outputs are capable of driving up to 15 LSTTL loads, providing significant output drive capability. It is designed for efficiency, with a maximum low power consumption of just 80μA and a low input current of 1μA. The device supports a clock frequency of up to 25MHz at 4.5V, enabling high-speed data transfer. Housed in a durable 16-pin PDIP package, it is designed for through-hole mounting on printed circuit boards and operates reliably across an extended temperature range from -40°C to 85°C.
