Product details
Overview
CY74FCT16374CTPVC from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 5.2 ns propagation delay (tPLH/tPHL), ±10% 5 V supply tolerance, and industrial temperature range (−40°C to +85°C). It drives high-capacitance loads and low-impedance backplanes in bus interface applications.
For engineers reviewing the CY74FCT16374CTPVC datasheet, CY74FCT16374CTPVC pinout, CY74FCT16374CTPVC application, or CY74FCT16374CTPVC equivalent, key selection criteria include output drive strength (64 mA sink / 32 mA source), Ioff partial-power-down support, ground bounce performance (VOLP < 1.0 V), and SSOP-48 package compatibility with legacy board layouts.
Technical Context
This device implements two independent 8-bit registers or one unified 16-bit register via shared clock (CLK) and output enable (OE) inputs. Its flow-through pinout minimizes trace routing complexity and supports high-speed signal integrity on dense PCBs.
The CY74FCT16374CTPVC uses FCT logic family architecture with edge-rate control circuitry to reduce system switching noise and ESD protection >2000 V. Ioff circuitry disables outputs during power-down to prevent current backflow, enabling safe hot-insertion in partial-power-down systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC | 5 V ± 10% - compatible with standard TTL/CMOS logic rails; no external regulator needed for 5 V systems |
| tPLH/tPHL | 2.0–5.2 ns - enables reliable operation at ≥100 MHz clock rates in registered bus interfaces |
| IOL/IOH | 64 mA sink / 32 mA source - sufficient to drive unterminated 50 Ω transmission lines or high-fanout backplanes |
| VOLP | <1.0 V at VCC = 5 V, TA = 25°C - limits ground bounce-induced logic errors in multi-load switching environments |
| Ioff | ±1 µA at VCC = 0 V - ensures isolation of powered-down sections in mixed-voltage or hot-swap subsystems |
| Operating Temp | −40°C to +85°C - qualified for industrial automation, telecom infrastructure, and embedded control applications |
| Package | 48-pin SSOP (O48), 300-mil width - drop-in replacement for legacy 48-pin SOIC footprints with improved thermal dissipation |
Pinout & Package
Package: 48-pin Shrink Small Outline Package (SSOP), JEDEC MO-118 compliant, body dimensions 18.54 mm × 9.40 mm × 2.79 mm (max height), lead pitch 25 mil (0.635 mm).

| 1–8, 17–24, 25–32, 41–48 | Data Inputs (D1–D8, D9–D16) | Asynchronous parallel data inputs for two independent 8-bit register banks |
| 9, 26 | Clock Inputs (1CLK, 2CLK) | Positive-edge-triggered clock inputs controlling latching of respective 8-bit banks |
| 10, 27 | Output Enable (1OE, 2OE) | Active-low three-state control enabling/disabling outputs per bank independently |
| 11–16, 19–24, 33–40 | Outputs (1O1–1O8, 2O1–2O8) | Registered, buffered outputs with 64 mA sink capability and controlled edge rates |
| 18, 31 | GND | Dual ground pins per bank reduce ground loop impedance and improve noise immunity |
| 12, 29 | VCC | Dual power pins per bank ensure stable voltage delivery under high-output switching transients |
Key Features
| Feature | Design Value |
|---|---|

|---|---|---|---|
| CY74FCT16374ATPVC | Slower 6.5 ns propagation delay; identical pinout, drive strength, and Ioff support | Suitable for cost-sensitive designs where 100 MHz timing margin is acceptable | Select when lower speed grade suffices and extended availability of SSOP-48 variant is required |
| CY74FCT162374CTPVC | 24 mA balanced drivers; lower ground bounce (VOLP < 0.6 V); no 64 mA sink capability | Optimized for transmission-line driving with reduced termination needs; not for high-current backplanes | Choose for differential signaling or stub-matched buses where current limiting and minimal undershoot are critical |
Compared with CY74FCT16374ATPVC, the CY74FCT16374CTPVC delivers tighter timing for high-frequency bus interfaces; versus CY74FCT162374CTPVC, it trades lower noise for higher drive strength-making it optimal for legacy backplane upgrades requiring direct replacement without layout change.

FAQ
What is the maximum clock frequency supported by CY74FCT16374CTPVC?
The CY74FCT16374CTPVC has a 5.2 ns maximum propagation delay (tPLH/tPHL) and 3.3 ns minimum clock pulse width (tW), supporting reliable operation up to 180 MHz in typical conditions. System-level timing must account for setup (2.0 ns) and hold (1.5 ns) margins relative to the clock edge. The CY74FCT16374CTPVC is not characterized for continuous operation above 200 MHz due to cumulative skew and ground bounce effects.
Does CY74FCT16374CTPVC support hot-swap or partial-power-down operation?
Yes, CY74FCT16374CTPVC integrates Ioff circuitry that disables outputs when VCC = 0 V, limiting current backflow to ±1 µA. This allows safe insertion into live backplanes and enables partial-power-down modes in modular systems. The CY74FCT16374CTPVC maintains this behavior across its full −40°C to +85°C operating range without external biasing.
Can CY74FCT16374CTPVC be used as two independent 8-bit registers?
Yes, CY74FCT16374CTPVC contains two functionally independent 8-bit register banks (Bank 1: Pins 1–8, 9, 10, 11–16; Bank 2: Pins 17–24, 26, 27, 25–32), each with dedicated clock (1CLK/2CLK) and output enable (1OE/2OE) inputs. This allows asynchronous latching and three-state control per bank-enabling flexible partitioning in multi-bus architectures without external logic.
What is the recommended PCB layout practice for minimizing ground bounce on CY74FCT16374CTPVC?
To minimize ground bounce on CY74FCT16374CTPVC, use separate GND pins (Pin 18 and Pin 31) for each register bank with dedicated low-inductance vias to internal ground planes. Place 0.1 µF ceramic decoupling capacitors within 3 mm of each VCC pin (Pin 12 and Pin 29), and route data/clock traces with controlled impedance and matched lengths. The CY74FCT16374CTPVC's edge-rate control reduces but does not eliminate the need for proper layout discipline.
Is CY74FCT16374CTPVC RoHS-compliant and lead-free?
Yes, CY74FCT16374CTPVC is RoHS-compliant and lead-free, with "Green (RoHS & no Sb/Br)" eco-plan designation and CU NIPDAU lead finish. It meets JEDEC MSL Level-1 (260°C peak reflow) and is qualified for standard Pb-free soldering processes. The CY74FCT16374CTPVC carries no exemptions and complies fully with EU Directive 2011/65/EU and China RoHS II.
