74VHC595MTCX

74VHC595MTCX is the 8-bit serial‑in/parallel‑out shift register with a storage latch (the classic 595) in the 74VHC family. It lets you expand a microcontroller’s I/O by chaining devices.
Key points:
- Function: DS (serial data in); SH_CP (shift clock); ST_CP (latch clock); MR (master reset, active low); OE (output enable, active low); Q0–Q7 plus Q7’ for cascading.
- Operation: On each rising SH_CP, DS data shifts into the internal register. On rising ST_CP, the register content is latched to the outputs. OE disables outputs; MR clears to zero.
- Characteristics: High‑speed CMOS, Vcc typically 2.0–6.0 V (commonly 3–5.5 V); TTL‑level inputs; suitable for cascading multiple devices.
- Package/variants: The MTCX suffix denotes a specific package/reel/temperature option—check the exact datasheet for package type and ordering options.
- Applications: LED displays and matrices, keypad interfaces, peripheral I/O expansion, any need to extend MCU I/O lines.
Note: For exact pinout, voltage range, and packaging of the MTCX variant, consult the supplier’s datasheet.

Equivalent parts (same function, different vendors/packaging):
- TI: SN74VHC595 (other package variants of the same device)
- NXP/Nexperia: 74VHC595
- STMicroelectronics: 74VHC595
- ON Semiconductor (and lineage from Fairchild): 74VHC595
Notes:
- 74HC595 or 74HCT595 can substitute in many cases if the supply voltage and input thresholds match your design. Always check packaging, footprint, voltage range, and timing.

- 8-bit serial-in, parallel-out shift register with 8-bit storage register
- Separate shift clock (SH_CP) and storage register clock (ST_CP) for data latching
- Serial data input (SER) and Q0–Q7 outputs
- Output enable (OE, active-low) for 3-state outputs
- Asynchronous clear (SRCLR/MR, active-low) to reset registers
- Data updated to outputs on ST_CP rising edge; shifting occurs on SH_CP
- Vcc range: 2.0 V to ~6.0 V (CMOS-compatible inputs)
- Low power consumption and high noise margin; suitable for high-speed operation
- Package: MTCX (16-pin) variant of the 74VHC595 family
Typical use: expand I/O, LED drivers, display drivers, and bus expansion with a daisy-chain via SER/SH_CP/ST_CP.

- Manufacturer: Nexperia.
- What kind of company: A global Dutch-based semiconductor company that designs and manufactures discrete devices and logic ICs (high-volume, low-power components; spin-off from Philips/NXP).

Applications of 74VHC595MTCX (8-bit serial-in, parallel-out shift register with latch):
- Microcontroller I/O expansion: add 8 outputs via a simple SPI-like interface.
- LED driving: indicators, segments, bars, dot-matrix displays; enables easy LED multiplexing/dimming.
- Display drivers: control 7-segment/LCD backplanes or small display arrays.
- Port expansion for keyboards, sensors, or auxiliary peripherals.
- Data routing and buffering: hold a parallel bus state for synchronous updates in digital systems.
- Any low-pin-count design needing a buffered, latched 8-bit parallel output from serial data.
