Product details
Overview
74HCT594D,118 from Nexperia is an 8-bit serial-in/parallel-out shift register with independent shift and storage registers, TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), 16-pin SO16 package, -40 °C to +125 °C operating range, and 92 MHz max clock frequency at VCC = 4.5 V - used in LED matrix drivers and remote control data latching.
For engineers reviewing the 74HCT594D,118 datasheet, 74HCT594D,118 pinout, 74HCT594D,118 application, or 74HCT594D,118 equivalent, this device supports cascaded serial-to-parallel conversion with dual-clock domain isolation, independent active-low reset for shift and storage registers, and robust ESD protection (HBM >2000 V).
Technical Context
The 74HCT594D,118 implements two synchronized but independently clocked 8-bit registers: a shift register accepting serial data on DS at SHCP rising edges, and a storage register transferring data from the shift register on STCP rising edges. This architecture enables glitch-free output updates and precise timing separation between data loading and output latching.
Its TTL-level input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) ensure compatibility with legacy 5 V microcontrollers and logic families, while its CMOS output stage delivers ±6 mA drive strength per Qn pin and ±4 mA on Q7S, supporting direct LED sinking without external buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HCT - TTL-compatible inputs, CMOS outputs, 4.5–5.5 V supply |
| Function | 8-bit serial-in/parallel-out shift register with separate storage register and dual clocks |
| Max Clock Frequency | 92 MHz at VCC = 4.5 V - enables high-speed data streaming in display controllers |
| Operating Temperature | -40 °C to +125 °C - qualified for automotive under-hood and industrial motor control environments |
| Output Drive | ±6 mA per parallel output (Q0–Q7); ±4 mA serial output (Q7S) - sufficient for direct LED interface |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 level 2 for board-level robustness |
| Propagation Delay | 18 ns (SHCP→Q7S), 18 ns (STCP→Qn) at VCC = 4.5 V - ensures tight timing margins in synchronous systems |
Pinout & Package
74HCT594D,118 uses the SOT109-1 (SO16) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm pitch, surface-mount, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–7, 15 | Q0–Q7 parallel outputs | 8-bit latch outputs; driven by storage register; enable simultaneous parallel data delivery |
| 8 | GND | Ground reference for all internal logic and output stages |
| 9 | Q7S serial output | Shift register MSB output; enables daisy-chaining multiple 74HCT594 devices |
| 10 | SHR shift reset | Active-low asynchronous clear of shift register only; no effect on storage register |
| 11 | SHCP shift clock | Rising-edge triggered; advances serial data through shift register stages |
| 12 | STCP storage clock | Rising-edge triggered; transfers full 8-bit content from shift to storage register |
| 13 | STR storage reset | Active-low asynchronous clear of storage register only; preserves shift register contents |
| 14 | DS serial input | Data input for shift register; sampled on SHCP rising edge |
| 16 | VCC | Positive supply rail (4.5–5.5 V); powers both logic and output stages |
Key Features
| Feature | Design Value |
|---|---|
| Independent shift/storage clocks | Enables precise timing control: data can be shifted ahead of output update, eliminating output glitches |
| TTL-compatible input thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V at 5 V - interoperates directly with 5 V MCUs and legacy logic without level shifters |
| Dual active-low reset pins | SHR and STR allow selective clearing of shift or storage register - critical for error recovery in communication protocols |
| Cascadable serial output (Q7S) | Supports unlimited expansion of parallel outputs via daisy-chain configuration - reduces MCU GPIO count |
| Wide temperature range | -40 °C to +125 °C operation - validated for automotive infotainment displays and industrial PLC I/O modules |
Applications
| LED Matrix Driver | Remote Control Data Latch |
|---|---|
Use Scenario: Driving 8×8 monochrome LED displays using microcontroller GPIO-limited interfaces. IC Role / Device Role / Timing Role: Serial-to-parallel converter that accepts SPI-like bitstream and presents stable 8-bit column/row data to LED driver ICs or discrete transistors. Use Value: Reduces required MCU pins from 16 (8 row + 8 column) to 3 (DS, SHCP, STCP), enabling compact PCB layout and lower BOM cost. | Use Scenario: Holding decoded infrared remote command codes for microcontroller polling or interrupt-triggered processing. IC Role / Device Role / Timing Role: Storage register acts as a hardware latch, capturing IR decoder output bits and holding them until firmware reads Q0–Q7. Use Value: Eliminates need for continuous IR signal sampling; allows low-power sleep modes between button presses. |
| Industrial I/O Expander | Test Equipment Pattern Generator |
Use Scenario: Adding isolated digital outputs to programmable logic controllers in factory automation systems. IC Role / Device Role / Timing Role: Shift register receives command bytes over RS-485 bus; storage register synchronizes output changes to system clock edges. Use Value: Provides deterministic, jitter-free output updates aligned to control system timing - essential for safety-critical actuator sequencing. | Use Scenario: Generating repetitive stimulus patterns for IC functional testing on ATE platforms. IC Role / Device Role / Timing Role: Cascaded 74HCT594D units form a programmable pattern memory; STCP triggers simultaneous output assertion across all channels. Use Value: Enables sub-20 ns output skew across 16+ channels - meets timing requirements for high-speed digital test vectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial-in/parallel-out shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC594D,118 | CMOS input thresholds (VIH = 3.15 V min at 4.5 V); wider 2–6 V supply range | Better suited for mixed-voltage systems (e.g., 3.3 V MCU driving 5 V peripherals) | Select when interfacing with 3.3 V logic or requiring broader VCC tolerance |
| SN74LV595AIPWR | 3.3 V optimized (1.65–5.5 V), lower ICC (10 μA typ), same pinout | Lower power consumption and improved noise immunity in battery-powered IoT nodes | Select for ultra-low static current and 3.3 V native operation |
Compared with 74HC594D,118 and SN74LV595AIPWR, the 74HCT594D,118 uniquely balances TTL compatibility, industrial temperature range, and proven cascade reliability - making it optimal for legacy 5 V control systems where input voltage margin and long-term availability are critical.

FAQ
What is the minimum setup time for DS relative to SHCP?
The minimum DS setup time (tsu) is 5 ns at VCC = 4.5 V and 25 °C, increasing to 6 ns across the full -40 °C to +85 °C range. This ensures reliable data capture on the SHCP rising edge without metastability, even under worst-case process/voltage/temperature corners.
Can SHCP and STCP be tied together?
Yes - tying SHCP and STCP together is explicitly supported and results in the shift register always being one clock pulse ahead of the storage register. This configuration simplifies timing in single-clock systems but eliminates independent control of data shifting versus output latching.
Does Q7S output reflect the shift register or storage register?
Q7S is the serial output of the shift register only - it reflects the MSB (Q7) of the shift register before transfer to the storage register. It does not mirror Q7 of the storage register, enabling true daisy-chaining without feedback interference.
What is the maximum output current per Qn pin?
Each parallel output (Q0–Q7) delivers up to 6 mA sink current (VOL ≤ 0.26 V at IO = 6 mA, VCC = 4.5 V) and 6 mA source current (VOH ≥ 3.98 V at IO = −6 mA, VCC = 4.5 V), verified across the full −40 °C to +125 °C operating range.
