Product details
Overview
CY74FCT16374CTPVCT from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit register capability, 5.2 ns max propagation delay (CLK to O), 64 mA sink / 32 mA source output drive, and industrial −40°C to +85°C operation. It serves as a high-speed bus interface register for driving high-capacitance loads and low-impedance backplanes in data acquisition and memory expansion systems.
For engineers reviewing the CY74FCT16374CTPVCT datasheet, CY74FCT16374CTPVCT pinout, CY74FCT16374CTPVCT application, or CY74FCT16374CTPVCT equivalent, key selection criteria include its 48-pin SSOP package, Ioff partial-power-down support, flow-through pinout architecture, and balanced noise performance with <0.5 ns output skew and <1.0 V ground bounce at 5 V.
Technical Context
The CY74FCT16374CTPVCT implements two independent 8-bit registers or one unified 16-bit register via shared CLK and OE inputs. Its TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V) and CMOS-level outputs operate at VCC = 5 V ±10%, with Ioff circuitry enabling safe partial-power-down by disabling outputs when VCC = 0 V.
It features edge-rate controlled outputs to suppress switching noise, 4.5 pF typical input capacitance, and 5.5 pF typical output capacitance. The device supports flow-through pinout for simplified PCB routing and meets >2000 V HBM ESD rating per MIL-STD-883 Method 3015.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - Enables direct compatibility with legacy 5-V TTL/CMOS systems without level-shifting. |
| Propagation Delay | 2.0–5.2 ns (CLK to O) - Supports ≥192 MHz clock rates in synchronous bus applications. |
| Output Drive | 64 mA sink / 32 mA source - Sufficient to drive 50-Ω transmission lines or high-fanout backplanes directly. |
| Output Skew | <0.5 ns - Ensures tight timing alignment across all 16 outputs, critical for parallel data capture integrity. |
| Ioff Support | Active at VCC = 0 V - Prevents backflow current during hot-swap or power sequencing, protecting upstream drivers. |
| Operating Temperature | −40°C to +85°C - Qualified for industrial control, test equipment, and embedded computing environments. |
| Package | 48-pin SSOP (O48), 300-mil body width - Standard footprint compatible with automated SMT assembly and IPC-7351 land patterns. |
Pinout & Package
48-pin Shrink Small Outline Package (SSOP), JEDEC MO-118 compliant, 300-mil body width (17.10 × 12.60 mm), 1.02 mm max height, gull-wing leads with 25.4 mil pitch. Pin 1 marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8, 17–24, 25–32, 41–48 | Data Inputs (D1–D16) | Asynchronous parallel data inputs; each tied to one register stage; TTL-compatible thresholds ensure robust noise margin. |
| 9, 26 | Clock Inputs (1CLK, 2CLK) | Positive-edge-triggered clocks controlling latching of respective 8-bit sections; internally synchronized for simultaneous update. |
| 10, 27 | Output Enable (1OE, 2OE) | Active-low three-state control per 8-bit bank; enables independent bus isolation or shared-bus multiplexing. |
| 11–16, 33–38 | Outputs (1O1–1O8, 2O1–2O8) | Three-state CMOS outputs with high sink/source capability; flow-through layout minimizes trace crossovers on PCB. |
| 19, 20, 39, 40 | GND | Four dedicated ground pins reduce ground bounce and improve signal integrity under heavy switching. |
| 21, 22, 37, 38 | VCC | Four dedicated power pins provide low-impedance supply paths and decoupling stability for 16-bit parallel switching. |
Key Features
| Feature | Design Value |
|---|---|
| Ioff partial-power-down | Disables outputs at VCC = 0 V, preventing damaging backflow current during hot-swap or mixed-voltage system power sequencing. |
| Edge-rate controlled outputs | Reduces simultaneous switching noise (SSN) and EMI emissions without external series resistors, easing EMC compliance. |
| Flow-through pinout | Input-to-output signal path follows linear left-to-right layout, eliminating layer jumps and minimizing trace length mismatch. |
| Low ground bounce | Typical VOLP < 1.0 V at VCC = 5 V - Maintains logic threshold margins even under full 16-bit switching load. |
| Industrial temperature range | −40°C to +85°C operation verified across full voltage and timing specs - suitable for uncontrolled ambient deployments. |

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 |
|---|---|---|---|
| CY74FCT162374CTPVCT | 24 mA balanced output drivers; lower ground bounce (<0.6 V); reduced switching noise; no high-drive sink capability. | Better suited for transmission-line driving and low-EMI applications; not recommended for high-capacitance backplane loads. | Select when signal integrity on long traces dominates over raw drive strength; verify termination strategy aligns with 24 mA drive. |
| CY74FCT16374ATPVCT | Slower 6.5 ns max propagation delay; identical pinout, drive strength, and Ioff functionality. | Acceptable where timing budget allows relaxed setup/hold margins; lower dynamic power at same frequency due to slower edges. | Choose for cost-sensitive industrial designs where 6.5 ns latency is acceptable and reduced switching noise is beneficial. |
Compared with CY74FCT162374CTPVCT, the CY74FCT16374CTPVCT delivers higher sink current for backplane loading but less optimized transmission-line behavior; versus CY74FCT16374ATPVCT, it provides tighter timing at the expense of slightly higher dynamic power.

FAQ
What is the maximum clock frequency supported by CY74FCT16374CTPVCT?
The CY74FCT16374CTPVCT has a maximum propagation delay of 5.2 ns (CLK to O), supporting reliable operation up to approximately 192 MHz in ideal conditions. Actual maximum frequency depends on board layout, load capacitance, and setup/hold timing margins - design validation requires measurement under target operating conditions using the CY74FCT16374CTPVCT's specified tSU = 2.0 ns and tH = 1.5 ns.
Does CY74FCT16374CTPVCT support partial power-down, and how is it implemented?
Yes, CY74FCT16374CTPVCT supports partial power-down via its Ioff circuitry. When VCC = 0 V, the outputs enter high-impedance state regardless of input or control pin states, preventing damaging current backflow. This feature is fully characterized per JEDEC JESD78 and validated across −40°C to +85°C, making CY74FCT16374CTPVCT suitable for hot-swap and multi-rail power sequencing applications.

CY74FCT16374CTPVCT provides 64 mA sink / 32 mA source drive optimized for high-capacitance backplanes, while CY74FCT162374CTPVCT offers balanced 24 mA drivers with lower ground bounce (<0.6 V) and built-in current-limiting resistors for transmission-line driving. Both share identical pinout, Ioff, and temperature range, but differ in drive strength, noise profile, and target interconnect topology.
Is CY74FCT16374CTPVCT pin-compatible with other members of the CY74FCT16374T family?
Yes, CY74FCT16374CTPVCT is pin-compatible with all speed grades (C, A, standard) and package variants (TSSOP Z48, SSOP O48) within the CY74FCT16374T family, including CY74FCT16374ATPVCT and CY74FCT16374TPVCT. All share identical 48-pin SSOP pinout, function table, and DC/AC electrical characteristics except propagation delay and power consumption.
What package options and RoHS status does CY74FCT16374CTPVCT have?
CY74FCT16374CTPVCT is supplied in a 48-pin SSOP (O48) package with 300-mil body width, green RoHS-compliant construction (Pb-free, no Sb/Br), CU NIPDAU lead finish, and JEDEC Level-1 MSL rating (unlimited floor life at ≤30°C/60% RH).
