Product details
Overview
CY74FCT162374CTPVC from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 24 mA balanced output drivers, 5.2 ns max propagation delay (CLK to O), and Ioff partial-power-down support - designed for high-speed bus interfacing in industrial backplane and transmission-line applications.
For engineers reviewing the CY74FCT162374CTPVC datasheet, CY74FCT162374CTPVC pinout, CY74FCT162374CTPVC application, or CY74FCT162374CTPVC equivalent, key selection criteria include output drive strength (24 mA), ground bounce performance (<0.6 V), TSSOP/SSOP package compatibility, and industrial temperature range (−40°C to +85°C).
Technical Context
This device implements two independent 8-bit registers or one unified 16-bit register via shared CLK and OE inputs. Its flow-through pinout minimizes trace skew and simplifies PCB layout for parallel data paths.
The Ioff circuitry disables outputs during power-down to prevent current backflow, while edge-rate control and integrated current-limiting resistors reduce system switching noise and eliminate need for external termination on transmission lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ± 10% - compatible with standard TTL/CMOS logic rails and industrial 5 V systems |
| Propagation Delay | 2.0–5.2 ns (CLK to O) - enables reliable operation at >100 MHz clock rates in synchronous buses |
| Output Drive | ±24 mA - balanced sourcing/sinking supports terminated transmission lines without external resistors |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - ensures signal integrity under heavy capacitive loading |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments including factory automation and motor control |
| Ioff Support | Active at VCC = 0 V - prevents damaging back-current during hot-insertion or partial power-down sequences |
| Input Hysteresis | 100 mV - improves noise immunity on slow-rising or noisy control signals like OE and CLK |
Pinout & Package
Package: 48-pin SSOP (O48), 300-mil body width, JEDEC MO-118 compliant, 1.2 mm max height, RoHS-compliant green finish (CU NIPDAU), MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-low three-state output enable | Independent control of each 8-bit register group; asserts high-impedance state when HIGH |
| 1CLK, 2CLK | Positive-edge clock input | Samples D inputs on rising edge; both clocks may be tied for 16-bit operation |
| 1D1–1D8, 2D1–2D8 | Data inputs | Asynchronous inputs latched on respective CLK edges; no internal pull-ups/pull-downs |
| 1O1–1O8, 2O1–2O8 | Three-state outputs | Driven low/high or placed in high-Z per OE state; 24 mA balanced drive reduces ground bounce |
| VCC, GND (×4) | Power and ground terminals | Dual VCC/GND pairs per register block minimize supply noise coupling between channels |
Key Features
| Feature | Design Value |
|---|---|
| Balanced 24 mA output drivers | Eliminates need for external series termination on PCB traces up to 15 cm, reducing BOM count and layout complexity |
| Reduced ground bounce (<0.6 V) | Enables stable multi-bit parallel transfers into high-capacitance loads without signal corruption or timing violations |
| Ioff partial-power-down support | Allows safe insertion/removal in live backplanes by disabling outputs when VCC = 0 V, preventing bus contention |
| Flow-through pinout | Input-to-output alignment across package halves simplifies routing and minimizes trace length mismatch in 16-bit buses |
| Edge-rate controlled outputs | Guarantees controlled slew rate to suppress EMI and crosstalk in dense interconnect layouts |
Applications
| Industrial Backplane Interface | Motor Control I/O Expansion |
|---|---|
Use Scenario: Interfacing microcontroller GPIO banks to modular I/O cards in PLC racks via parallel backplane. IC Role / Device Role / Timing Role: 16-bit registered buffer isolating MCU from backplane capacitance and noise; synchronized by system clock.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit registered buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16374CTPVC | 64 mA sink / 32 mA source drive; higher ground bounce (≤1.0 V); optimized for heavy capacitive loads | Better suited for driving unterminated backplanes or high-C bus stubs; less ideal for transmission-line matching | Select when load capacitance exceeds 50 pF per line or termination is impractical |
| SN74ALVCH162374DGGR | 3.3 V only; ±24 mA drive; 3.5 ns max tPLH; lower ICC (1.5 µA typical) | Targets modern low-voltage systems; not 5 V tolerant; requires level-shifting for legacy 5 V buses | Choose for new 3.3 V designs where power efficiency and smaller footprint (TSSOP-48) are priorities |
Compared with CY74FCT16374CTPVC, CY74FCT162374CTPVC offers tighter ground bounce control and built-in termination capability for clean signal integrity on controlled-impedance lines; versus SN74ALVCH162374DGGR, it maintains full 5 V compatibility and industrial temperature robustness but consumes more quiescent current.

FAQ
What is the maximum clock frequency supported by CY74FCT162374CTPVC?
CY74FCT162374CTPVC has a minimum CLK pulse width of 3.3 ns (HIGH or LOW), supporting guaranteed operation up to 151 MHz. Real-world timing margin depends on setup/hold (2.0 ns / 1.5 ns) and board-level signal integrity; for 100 MHz synchronous buses, CY74FCT162374CTPVC provides robust timing headroom.
Does CY74FCT162374CTPVC support hot-swap or partial-power-down operation?
Yes, CY74FCT162374CTPVC features Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during live insertion or partial system power-down - a critical requirement for modular industrial backplanes and redundant power architectures.
What is the difference between CY74FCT162374CTPVC and CY74FCT16374CTPVC?
CY74FCT162374CTPVC uses 24 mA balanced drivers with current-limiting resistors for reduced ground bounce (<0.6 V) and transmission-line optimization, while CY74FCT16374CTPVC delivers 64 mA sink / 32 mA source drive for heavy capacitive loads but exhibits higher ground bounce (≤1.0 V). Both share identical pinout and timing specs.
Is CY74FCT162374CTPVC RoHS compliant and what is its moisture sensitivity level?
Yes, CY74FCT162374CTPVC is RoHS-compliant (Green: Pb-free, no Sb/Br) with CU NIPDAU lead finish and JEDEC MSL Level-1 (unlimited floor life at ≤30°C/60% RH), making it suitable for standard reflow assembly without dry-pack requirements.
Can CY74FCT162374CTPVC be used as two independent 8-bit registers?
Yes, CY74FCT162374CTPVC contains two functionally independent 8-bit register sections (1D–1O and 2D–2O), each with dedicated CLK and OE inputs. Connecting 1CLK/2CLK and 1OE/2OE enables unified 16-bit operation; keeping them separate allows asynchronous 8-bit latching in mixed-timing systems.
