Vue d'ensemble

Description

CD74HC595M96 is an 8-bit serial-in, parallel-out shift register with a storage latch from the 74HC CMOS family. It lets you expand microcontroller I/O by shifting in 8 bits and latching them to outputs.
Key features
- 8 D-type flip-flops in a shift register with a separate storage/latch register
- Serial data input (DS), shift clock (SH_CP), and latch clock (ST_CP)
- 8 outputs Q0–Q7 with a serial out (Q7’) for daisy chaining
- Output Enable (OE, active low) and Master Reset (MR, active low)
- 3-state outputs when OE is high
- Typical supply: 2–6 V (CMOS)
- Fast CMOS operation; can cascade to drive many outputs
Common use
- Expand I/O for microcontrollers
- Driving LED matrices, displays, or parallel peripherals
Pinout/package variants vary (e.g., DIP/SOIC); “M96” denotes a specific package/variant—check the datasheet for exact pinout and packaging details.

Features

Key features of CD74HC595M96:
- 8-bit serial-in, parallel-out shift register with an internal storage register (latch)
- DS serial data input; SH_CP clocks data into the shift register
- ST_CP latch clock transfers data from storage to output pins
- 3-state outputs controlled by OE (Output Enable)
- Asynchronous master reset/clear (MR) to clear the registers
- Q7’ (serial) output for easy daisy-chaining
- Wide supply range (HC family): typically 2–6 V, compatible with 5 V logic
- High-speed CMOS performance with low power consumption
- Suitable for LED drivers, display/port expansion, and general I/O buffering (with current-limited loads)
Note: Provides standard 74HC595 functionality in a compact package; check datasheet for exact electrical specs and pinout.

Package

The CD74HC595M96 is supplied in a 16‑pin SOIC (small‑outline) surface‑mount package (SOIC‑16).

Pinout

Pin count: 16 pins.
Function (concise):
- 8-bit serial-in, parallel-out shift register with storage (latch) register (provides 8 parallel outputs, Q0–Q7).
- Serial data input (SER) for loading bits.
- Serial data output (Q7′ / QH′) for cascading multiple devices.
- Shift clock (SRCLK / SH_CP) to shift bits into the shift register.
- Latch clock (RCLK / ST_CP) to copy shift register into output latch (updates outputs).
- Output enable (OE, active LOW) to tri-state outputs.
- Asynchronous clear (SRCLR, active LOW) to reset the shift register.
- Power pins: VCC and GND.
Common use: expand microcontroller GPIOs, daisy-chainable for many outputs.
