SN74AHC595DR  

Shift Registers

The SN74AHC595DR is a high-speed 8-bit shift register manufactured by Texas Instruments. It is a part of the 74AHC/HCT series of logic devices, which are designed to operate with low voltage and low power consumption while providing high performance.

Description:

The SN74AHC595DR is a serial-in, parallel-out shift register that can store and transmit 8 bits of data at a time. It has a serial input (DS) for shifting data into the register, a parallel input (D0 to D7) for loading data directly, and a parallel output (Q0 to Q7) for retrieving the stored data. The device also features a storage register and a shift register, allowing it to store and shift data simultaneously.

Features:

1. 8-bit serial-in, parallel-out shift register
2. 3-state outputs for flexible bus applications
3. Compatible with TTL and CMOS logic levels
4. Wide operating voltage range (2V to 6V)
5. Low power consumption (typical 2.2mA at 5V)
6. High-speed operation (typical 7.5ns propagation delay at 5V)
7. Active-low serial and parallel load control inputs (SH_CP and ST_CP)
8. Active-low output enable control input (OE)
9. Active-low master reset input (MR)

Applications:

1. LED display scanning and control in multiplexed LED displays
2. Data storage and transmission in serial communication systems
3. Shift register applications in digital signal processing
4. Data buffering and level conversion in digital circuits
5. Expanding the number of parallel outputs from a microcontroller or processor
6. Driving relays, solenoids, or other high-current loads
7. Synchronization of data in digital systems

The SN74AHC595DR is a versatile and efficient shift register that can be used in a wide range of applications where data storage, transmission, and manipulation are required. Its compatibility with both TTL and CMOS logic levels, low power consumption, and high-speed operation make it suitable for various digital designs.
