The 74V595MTC is an 8-bit serial-in, serial or parallel-out shift register with output latches and 3-STATE outputs from Fairchild Semiconductor (now ON Semiconductor). This device is commonly used for expanding I/O capabilities in digital systems, such as driving LEDs, controlling relays, and interfacing with displays.

Applications

• LED displays
• Relay drivers
• Digital control circuits
• Serial-to-parallel data conversion

Features

• Serial-to-Parallel Conversion: Converts serial data into parallel data
• 8-Bit Storage Register: Stores 8 bits of data
• 3-STATE Outputs: Allows for easy connection to buses
• Output Latches: Provides stable outputs
• Low Power Consumption: ICC = 4 µA (max) at VCC = 5V

Benefits

• I/O Expansion: Extends the number of available I/O ports.
• Simplified Wiring: Reduces the number of wires required for data transfer.
• Versatile Control: Can be used in a variety of digital control applications.
• Stable Outputs: Output latches ensure stable data outputs.
• Wide Operating Voltage Range: Operates from 2V to 6V.

Additional Details

The 74V595MTC contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks are provided for both the shift register (SH_CP) and the storage register (ST_CP). A serial output (Q7S) is provided for cascading devices. The 3-STATE outputs are controlled by the output enable (OE) input. When OE is LOW, the outputs are enabled; when OE is HIGH, the outputs are in a high-impedance state. The operating temperature range is typically -40°C to +85°C. This device is ideal for applications where a limited number of I/O pins need to control a larger number of devices.
