MM74HC595MTCX

MM74HC595MTCX is a variant of the 74HC595 8-bit serial-in/parallel-out shift register with a storage (latch) register. It lets you expand microcontroller I/O with few pins.
Key features:
- DS: serial data input
- SHCP: shift clock; data shifts into the 8-bit shift register on rising edge
- STCP: latch clock; on its rising edge the shift register contents are copied to the 8 outputs (Q0–Q7)
- OE: output enable (tri-states outputs when disabled)
- MR: asynchronous master clear (resets outputs)
- Q7' for cascading to another device
Typical use: drive LEDs, LED matrices, displays, or expand I/O for keyboards and other peripherals. It’s simple to cascade: connect Q7’ to the DS of the next device.
Electricals: part of the 74HC family, generally 2–6V operation (best at 4.5–5.5V). Exact timing, current limits, and package details depend on the MTCX variant—check the manufacturer’s datasheet for the exact package and specs.
In short: an 8-bit, serial-input, parallel-output expander with latch, ideal for low-pin-count I/O expansion.

Here are the key features of MM74HC595MTCX (a CMOS 8-bit shift register with storage and 3-state outputs):
- 8-bit serial-in, parallel-out shift register with an 8-bit storage register
- 3-state outputs (OE pin active-low) to disable outputs
- DS: serial data input; SH_CP: shift register clock; ST_CP: storage/register latch clock
- MR: asynchronous master reset clears both shift and storage registers
- Q7’ serial output for easy daisychaining to expand bits
- Outputs update from storage register on ST_CP (latched drive)
- Wide supply range: typically 2 V to 6 V (CMOS compatible)
- High-speed CMOS performance (fmax in the tens of MHz range depending on Vcc)
- Low power consumption characteristic of CMOS devices
- Suitable for daisy-chain LED drivers, I/O expansion, and general-purpose buffering
- Available in standard small-outline/micro packages (as per MTCX variant)
Note: exact electrical specs (voltages, current per pin, timing) vary by supplier revision; consult the specific datasheet for the MM74HC595MTCX variant you’re using.

16-pin molded small-outline package (SOIC-16).

Pin count: 16 pins.
Function (concise): The MM74HC595MTCX is an 8‑bit serial‑in, serial/parallel‑out shift register with a separate storage (latch) register and active‑low tri‑state outputs. It accepts serial data (SER/DS), shifts it on the shift‑clock (SRCLK), latches the 8‑bit pattern to the outputs on the register clock (RCLK), and provides a serial output (Q7′) for cascading. Key control pins: SRCLR\ (active‑low reset), OE\ (active‑low output enable), VCC and GND; outputs QA–QH are the parallel outputs.

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (headquartered in the Netherlands) that designs and produces discrete components, MOSFETs, logic ICs (including 74HC family devices), and other analog/mixed-signal products.

Common application areas for MM74HC595MTCX (8-bit shift register with latch):
- I/O expansion for microcontrollers with limited pins
- Driving LED displays (7-segment, dot-matrix, bar graphs) and simple LED drivers
- Serial-to-parallel data conversion with a latch for synchronized outputs
- Data buffering and timing control in digital circuits
- Interfacing processors to parallel peripherals while reducing pin count
- Driving low-current loads with external buffers/relays (via suitable drivers)
