Product details
Overview
CY74FCT162374TPVCT from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit bank configuration, 24 mA balanced output drivers, Ioff partial-power-down support, and 5.2 ns typical propagation delay (CLK to O) at VCC = 5 V. It serves as a high-speed bus interface register in industrial backplane and transmission-line applications.
For engineers reviewing the CY74FCT162374TPVCT datasheet, CY74FCT162374TPVCT pinout, CY74FCT162374TPVCT application, or CY74FCT162374TPVCT equivalent, key selection criteria include its 24 mA balanced drive capability, sub-0.6 V ground bounce (VOLP), flow-through pinout for PCB layout simplification, and SSOP-48 industrial-grade packaging.
Technical Context
The CY74FCT162374TPVCT implements two independent 8-bit D-register banks sharing common clock (CLK) and output-enable (OE) inputs, enabling flexible 8- or 16-bit operation. Its Ioff circuitry disables outputs during power-down to prevent current backflow.
It features current-limiting resistors integrated into 24 mA balanced output drivers-reducing need for external termination, minimizing undershoot, and suppressing ground bounce. Designed specifically for driving controlled-impedance transmission lines, it operates across −40°C to +85°C at VCC = 5 V ±10%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - fixed single-supply operation compatible with TTL/CMOS logic families |
| Propagation Delay (tPLH/tPHL) | 2.0–5.2 ns - enables >100 MHz register clocking in high-speed digital systems |
| Output Drive Strength | ±24 mA - balanced sourcing/sinking supports clean signal integrity on 50 Ω transmission lines |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - minimizes noise coupling in dense multi-channel layouts |
| Ioff Support | Enabled - prevents damaging backflow current when VCC = 0 V, critical for hot-swap and partial-power-down systems |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments without derating |

FAQ
What is the maximum clock frequency supported by CY74FCT162374TPVCT?
The CY74FCT162374TPVCT has a minimum CLK pulse width of 3.3 ns (HIGH or LOW), supporting reliable operation up to approximately 150 MHz. This is derived from tW = 3.3 ns, implying fMAX ≈ 1 / (2 × tW) ≈ 151 MHz. Real-world timing margins and board-level signal integrity may require derating to 100–125 MHz in production systems using CY74FCT162374TPVCT.
Does CY74FCT162374TPVCT support hot-swap operation?
Yes, CY74FCT162374TPVCT supports hot-swap via its Ioff circuitry, which disables outputs when VCC = 0 V, preventing damaging current backflow from live bus lines into the unpowered device. This feature is fully specified over −40°C to +85°C and makes CY74FCT162374TPVCT suitable for modular chassis and field-replaceable unit designs.
What is the purpose of the dual OE (1OE and 2OE) inputs on CY74FCT162374TPVCT?
The dual active-low output-enable inputs (1OE and 2OE) allow independent three-state control of each 8-bit register bank. This enables selective bus isolation-for example, holding one 8-bit channel in high-Z while updating the other-without requiring additional logic or clock gating. This functionality is intrinsic to CY74FCT162374TPVCT's architecture and enhances system-level flexibility in multiplexed data paths.
Can CY74FCT162374TPVCT be used with 3.3 V logic levels?
No, CY74FCT162374TPVCT is strictly a 5 V device (VCC = 5 V ±10%) and is not 3.3 V tolerant. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) are TTL-compatible but do not meet 3.3 V CMOS logic level requirements. Using CY74FCT162374TPVCT with 3.3 V drivers risks marginal or non-functional operation and is outside its specified operating conditions.
How does the flow-through pinout of CY74FCT162374TPVCT improve PCB layout?
The flow-through pinout aligns data inputs (1D1–1D8, 2D1–2D8) and corresponding outputs (1O1–1O8, 2O1–2O8) on opposite sides of the SSOP-48 package, enabling straight, short, and length-matched traces without vias or layer changes. This reduces crosstalk, maintains impedance control, and simplifies routing in dense 16-bit bus implementations-directly enhancing signal integrity in designs using CY74FCT162374TPVCT.
