Nexperia USA Inc. 74LVC595APW,112

Overview

74LVC595APW,112 from Nexperia is an 8-bit serial-in/parallel-out shift register with separate shift and storage clocks, 3-state outputs, asynchronous master reset (MR), and Schmitt-trigger inputs. It operates from 1.2 V to 3.6 V, accepts 5.5 V-tolerant inputs, and supports mixed-voltage interfacing in LED matrix drivers and microcontroller GPIO expanders.

For engineers reviewing the 74LVC595APW,112 datasheet, 74LVC595APW,112 pinout, 74LVC595APW,112 application, or 74LVC595APW,112 equivalent, key selection criteria include propagation delay (≤7.7 ns at 3.6 V), IOFF-enabled partial power-down, -40 °C to +125 °C operation, and TSSOP16 package compatibility with high-density PCB layouts.

Technical Context

The device implements two independent synchronous registers: an 8-stage shift register clocked by SHCP and a storage latch clocked by STCP, enabling pipelined data transfer. MR asynchronously clears only the shift register, while OE independently controls 3-state output enable without affecting internal state.

Inputs tolerate up to 5.5 V regardless of VCC (1.2–3.6 V), allowing direct connection to 5 V logic; Schmitt-trigger thresholds ensure noise immunity on slow-rising signals, and IOFF circuitry disables outputs during power-down to prevent backflow current.

FAQ

Can 74LVC595APW,112 be used with a 5 V microcontroller SPI interface?

Yes - its inputs are overvoltage tolerant up to 5.5 V regardless of VCC (1.2–3.6 V), allowing direct connection to 5 V SPI clock, data, and latch signals without level shifters. Outputs remain compatible with 3.3 V logic when VCC = 3.3 V, and drive strength (±24 mA) supports direct LED or relay control.

What happens to the parallel outputs during power-down?

When VCC drops to 0 V, the IOFF circuitry automatically disables all outputs, limiting OFF-state leakage to ≤20 μA. This prevents backflow current into the device from other powered rails - a critical safety feature in multi-supply systems and hot-swap applications.

How does the dual-clock architecture prevent output glitches?

Separate SHCP (shift) and STCP (storage) clocks decouple serial loading from parallel output updates. Data shifts through the 8-bit register on SHCP edges, then transfers atomically to the output latches on STCP edges - eliminating intermediate states and ensuring glitch-free transitions on all Q0–Q7 lines.

Is the TSSOP16 package (SOT403-1) RoHS and REACH compliant?

Yes - Nexperia certifies the 74LVC595APW,112 as fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SOT403-1 package uses lead-free matte tin terminations and halogen-free molding compound, with full material declarations available upon request.
