Product details
Overview
M74HC592TTR from STMicroelectronics is a high-speed CMOS 8-bit register counter with parallel load, binary counting, direct clear, and ripple-carry output functionality. It features dual independent positive-edge clocks (RCK for register, CCK for counter), operates from 2V to 6V, delivers 53 MHz max clock frequency at 6V, and provides symmetrical 4 mA output drive. Used in digital timing control and address sequencing in legacy industrial controllers.
For engineers reviewing the M74HC592TTR datasheet, M74HC592TTR pinout, M74HC592TTR application, or M74HC592TTR equivalent, this page delivers verified electrical parameters, TSSOP-16 pin mapping, functional role in synchronous data staging and binary counting, and validated drop-in alternatives for legacy system maintenance.
Technical Context
The M74HC592 integrates an 8-bit parallel-input storage register cascaded to an 8-bit binary counter, each with separate edge-triggered clocks (RCK and CCK). Its RCO output enables synchronous multi-stage expansion via CCKEN chaining, while CLOAD and CCLR provide asynchronous load and reset control.
Designed using silicon gate C2MOS technology, it achieves balanced tPLH/tPHL propagation delays, 28% VCC noise immunity, and low 4 µA ICC quiescent current at 25°C - enabling reliable operation in noisy industrial environments with wide supply tolerance (2–6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2 V to 6 V - supports mixed-voltage logic interfacing and battery-backed operation down to 2 V. |
| fMAX | 53 MHz (typ.) at VCC = 6 V - enables high-throughput counting in real-time control loops. |
| IOH / IOL | ±4 mA (min) - drives standard TTL loads and multiple CMOS inputs without buffering. |
| VNIH / VNIL | 28% VCC (min) - ensures robust noise rejection in electrically harsh factory settings. |
| tPLH / tPHL (CCK→RCO) | 18 ns / 28 ns (max) at VCC = 6 V - guarantees deterministic carry propagation across counter stages. |
| ICC (quiescent) | 4 µA (max) at TA = 25°C - minimizes standby power in always-on embedded systems. |
| RCO Logic | QA′·QB′·QC′·QD′·QE′·QF′·QG′·QH′ - active-low ripple carry enables synchronous 16-bit+ counter expansion. |
Pinout & Package
Package: TSSOP-16 (4.9 × 6.4 mm, 0.65 mm pitch), RoHS-compliant, surface-mount, optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–7, 15 (A–H) | Data Inputs | Parallel 8-bit input bus for loading counter value or register content. |
| 8 | GND | Ground reference for all internal logic and I/O circuits. |
| 9 | RCO | Ripple Carry Output - active-low terminal indicating overflow of 8-bit count (all outputs high). |
| 10 | CCLR | Asynchronous Counter Clear - forces counter to zero regardless of clock state. |
| 11 | CCK | Counter Clock Input - positive-edge triggered; advances count when CCKEN = H. |
| 12 | CCKEN | Counter Clock Enable - gates CCK; counter advances only when CCKEN = H. |
| 13 | RCK | Register Clock Input - positive-edge triggered; latches A–H data into register. |
| 14 | CLOAD | Counter Load Input - transfers register contents to counter on next CCK edge. |
| 16 | VCC | Positive Supply Voltage - powers all internal logic and output drivers (2–6 V). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent clocks | RCK and CCK allow decoupled register staging and counter advancement - essential for pipelined address generation. |
| Direct load & clear | CLOAD and CCLR enable precise initialization and error recovery without disrupting clock domain timing. |
| Ripple-carry expansion | RCO output logic matches 74-series standards, permitting seamless multi-stage binary counters up to 64 bits. |
| High noise immunity | 28% VCC input threshold prevents false triggering from EMI in motor-drive or relay-control environments. |
| Low-power CMOS design | 4 µA max ICC at 25°C reduces thermal load and extends battery life in portable test equipment. |
Applications
| Industrial PLC Address Sequencing | Legacy Test Equipment Timing Control |
|---|---|
|
Use Scenario: Generating sequential memory addresses in ladder-logic scan cycles within DIN-rail mounted PLCs. IC Role / Device Role / Timing Role: 8-bit register holds base address; counter increments per instruction fetch with RCO enabling page wrap. Use Value: Eliminates external glue logic by integrating register + counter + carry in one TSSOP-16 package, reducing board area by 35% vs discrete 74HC163 + 74HC574 solution. |
Use Scenario: Controlling step-and-repeat motion in aging automated test fixtures with fixed 8-bit resolution. IC Role / Device Role / Timing Role: Serves as programmable interval timer - loaded via A–H, decremented on trigger pulses, with RCO signaling completion. Use Value: Enables deterministic 256-step timing sequences with sub-20 ns propagation delay consistency across temperature (-55°C to +125°C). |
| Motor Phase Encoder Indexing | Legacy Communication Protocol Sync |
|
Use Scenario: Tracking commutation states in 3-phase BLDC motor controllers using Hall sensor patterns. IC Role / Device Role / Timing Role: Counts rising edges from encoder outputs; RCO triggers interrupt on full rotation (256 counts). Use Value: Provides hardware-based index detection with no MCU overhead - critical for real-time torque ripple suppression. |
Use Scenario: Synchronizing legacy serial frame boundaries in RS-485 fieldbus nodes with fixed packet length. IC Role / Device Role / Timing Role: Generates bit-count enable signals for UART shift registers using CCKEN gating and RCO rollover. Use Value: Ensures bit-aligned framing without software polling, improving protocol jitter margin by >15 ns over firmware-only solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit register counter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC592N | DIP-16 package only; identical AC/DC specs and pinout; no TSSOP variant available. | Requires through-hole assembly; unsuitable for high-density SMT production. | Select when legacy DIP sockets or hand-soldered prototyping are required. |
| 74AC592PC | Faster tPLH/tPHL (12 ns typ. at 5 V); higher ICC (8 µA typ.); wider VCC range (2–6 V same). | Better suited for high-speed clock domains (>60 MHz), but increases static power by 100%. | Choose only if propagation delay reduction outweighs power budget constraints. |
Compared with SN74HC592N and 74AC592PC, M74HC592TTR uniquely balances SMT compatibility, ultra-low quiescent current, and industrial temperature support - making it optimal for space-constrained, battery-sensitive, or extended-temperature legacy upgrades.

FAQ
Is M74HC592TTR functionally identical to the through-hole M74HC592B1R?
Yes - M74HC592TTR and M74HC592B1R share identical logic function, DC/AC specifications, and pin-to-pin mapping. The only difference is package: TSSOP-16 versus DIP-16. Electrical performance (propagation delay, drive strength, noise immunity) is fully aligned per STMicroelectronics' datasheet Rev. 14.
Can M74HC592TTR operate reliably at -55°C?
Yes - the device is rated for operation from -55°C to +125°C per its Recommended Operating Conditions table. All key parameters including fMAX, tPLH/tPHL, and VIH/VIL are guaranteed across this full range, confirmed in the "-55 to 125°C" column of the DC and AC characterization tables.
What is the exact logic equation for RCO, and how does it behave during counting?
RCO = QA′·QB′·QC′·QD′·QE′·QF′·QG′·QH′, where QA′–QH′ are internal counter outputs. RCO goes low only when all eight counter bits are high (i.e., count = 255), then returns high on the next clock edge - providing a precise, glitch-free carry signal for multi-stage chaining.
Does CLOAD require CCK to be inactive during transfer?
No - CLOAD is asynchronous with respect to CCK. When CLOAD is asserted (high), the next rising edge of CCK transfers the current register contents (A–H) into the counter, regardless of prior counter state. This allows deterministic reinitialization mid-sequence without pausing the clock domain.
