概述

Description

The 74VHC595MTCX is an 8-bit serial-in, parallel-out shift register with a storage latch and tri-state outputs (a member of the 74VHC family). It lets you expand microcontroller I/O.
Key features:
- Inputs/outputs: DS (data in), SH_CP (shift clock), ST_CP (latch/storage clock), OE (output enable, active low), MR (master reset, active low); Q0–Q7 outputs; Q7’ serial out for daisy chaining.
- Operation: Data on DS is shifted into the shift register on rising SH_CP. On rising ST_CP, the shift register contents are latched to the storage register and appear on Q0–Q7. OE enables/disables outputs; MR asynchronously clears both registers.
- Electrical: VCC range ≈ 2.0–6.0 V (CMOS), TTL-compatible inputs, moderate drive capability per pin.
- Package: MTCX denotes a compact SMT package variant.
Applications: expanding I/O, LED displays, register cascades, memory-mapped interfaces.
For exact pinout, timing, and current specs, consult the device datasheet.

Features

Key features of 74VHC595MTCX (8-bit shift register with storage):
- 8-bit serial-in, parallel-out shift register with 8-bit storage register
- Separate latch input (ST_CP) to update outputs from storage register
- Serial data input (DS) and clock input (SH_CP)
- Output enable (OE, active-low) for 3-state outputs
- Master/reset/clear input (MR or SRCLR) to asynchronously reset registers
- Q7′ serial output for cascading
- 3-state outputs allow high-impedance when disabled
- Wide operating voltage: typically 2.0 V to 6.0 V (CMOS VHC family)
- High-speed CMOS with low power consumption
- Ideal for I/O expansion, LED driving, and display/graphics interfaces
- Daisy-chain capability via Q7′ for extending more bits
Note: Polarity of MR/SRCLR and specific package details vary by variant; consult datasheet for exact pinout and active levels.

Package

The 74VHC595MTCX is a 16-pin surface-mount SOIC/SOP package (SO-16), supplied in tape-and-reel (MTCX) format.

Pinout

The 74VHC595MTCX is a 16-pin device. It is an 8-bit serial-in, serial/parallel-out shift register with storage latches and tri‑state outputs. Key pins and functions:
- VCC, GND: power supply
- SER (DS): serial data input
- SRCLK (SH_CP): shift register clock (serial data shift)
- RCLK (ST_CP): storage register clock / latch (transfers shift register to outputs)
- Q7' (QH’): serial data output (cascade to next device)
- OE (active low): output enable (tri‑states outputs when high)
- MR (active low): master reset (clears shift register when low)
- Q0–Q7 (QA–QH): parallel outputs
Typical packages: 16‑pin SOIC/DIP/TSSOP.

Manufacturer

Manufacturer: Nexperia (Nexperia B.V.).
What kind of company: Nexperia is a Dutch semiconductor manufacturer specializing in standard logic ICs, discrete semiconductors (diodes, transistors, MOSFETs) and other high-volume components for automotive, industrial and consumer electronics.

Application

74VHC595MTCX is an 8-bit serial‑in/parallel‑out shift register with a latch. Typical applications: expand microcontroller I/O with minimal pins; drive LEDs, LED matrices and 7‑segment displays via a common data clock; serialize data and then load it into parallel outputs; cascade multiple devices for larger I/O banks; serve as a fast, low‑cost data buffer/storage in embedded systems; provide a simple digital interface for timing‑critical control and indicator circuits (with appropriate current limiting).
