The SN74AHC595NSR is an Integrated Circuit (IC) component that belongs to the AHC family of devices. It is a shift register with an output-latch designed to be used in serial-to-parallel or parallel-to-serial data conversion applications. Here is an overview of the key features of the SN74AHC595NSR IC component:
1. Shift Register: The SN74AHC595NSR has an 8-bit shift register designed to convert serial input data into parallel output data. It has a serial input (SER) pin and a serial output (Q7S) pin for cascading multiple devices.
2. Serial Data Transfer: The IC component supports serial data transfer with a clock input (SRCLK). It uses the rising edge of the clock input to shift in the serial data from the SER pin.
3. Storage Latches: The SN74AHC595NSR has an 8-bit storage latch for parallel data output, which can be controlled using the RCLK (Register Clock) input pin. When RCLK transitions from high to low, the parallel output data gets latched and remains stable until the next RCLK transition.
4. Output Enable: The IC component features an active-low output enable (OE) input pin, which, when low, enables the output pins to drive their respective logic levels. When high, the outputs are in a high-impedance state
