Product details
Overview
CY74FCT162374ATPVC from Texas Instruments is a 16-bit edge-triggered D-type register with dual 8-bit bank capability, 24 mA balanced output drivers, 6.5 ns max propagation delay (CLK to O), and Ioff partial-power-down support. It operates at 5V ±10% across −40°C to +85°C and is optimized for high-speed transmission-line interfacing in industrial bus systems.
For engineers reviewing the CY74FCT162374ATPVC datasheet, CY74FCT162374ATPVC pinout, CY74FCT162374ATPVC application, or CY74FCT162374ATPVC equivalent, key selection criteria include its 24 mA matched drive strength, sub-0.6 V ground bounce (VOLP), flow-through pinout for PCB routing simplicity, and SSOP-48 package compatibility with legacy 300-mil pitch layouts.
Technical Context
This device implements two independent 8-bit registers sharing common clock and output-enable inputs, enabling flexible 8- or 16-bit data latching. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, meeting industrial partial-power-down requirements.
The 24 mA balanced sink/source drivers incorporate integrated current-limiting resistors, reducing need for external termination and minimizing undershoot and ground bounce-critical for clean signal integrity on controlled-impedance traces and backplanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 5 V ±10% - Ensures stable operation across industrial supply variations without regulation. |
| Propagation Delay | 6.5 ns max (CLK to O) - Supports ≥150 MHz system clock domains with timing margin. |
| Output Drive | ±24 mA balanced - Enables direct driving of 50 Ω transmission lines without external resistors. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - Reduces noise coupling into adjacent signals and power rails. |
| Operating Temp | −40°C to +85°C - Qualified for extended industrial ambient environments. |
| Ioff Support | Active at VCC = 0 V - Prevents damaging current flow during hot-insertion or partial system power-down. |
| ESD Rating | >2000 V HBM - Provides robust handling protection during assembly and field service. |
Pinout & Package
Package: 48-pin SSOP (DL), 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 output enable (dual banks) | Independent control of 8-bit output groups; enables time-multiplexed bus sharing. |
| 1CLK, 2CLK | Positive-edge clock inputs (dual banks) | Edge-triggered latching per bank; allows staggered or synchronized capture. |
| 1D1–1D8, 2D1–2D8 | Data inputs (two 8-bit banks) | Flow-through layout aligns inputs/outputs on opposite sides for minimal trace length. |
| 1O1–1O8, 2O1–2O8 | Three-state outputs (dual banks) | High-impedance state activated by OE; supports bidirectional bus arbitration. |
| VCC, GND (×4 each) | Power and ground terminals | Distributed supply/return pins reduce simultaneous switching noise and improve PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced 24 mA drivers | Matched sink/source strength eliminates asymmetry-induced jitter and reduces termination component count. |
| Edge-rate control | Controlled slew rate minimizes EMI and crosstalk in dense PCB layouts. |
| Typical output skew < 0.5 ns | Ensures deterministic timing across all 16 outputs for synchronous data capture. |
| Ioff partial-power-down | Prevents back-current when VCC = 0 V, supporting hot-swap and mixed-voltage system designs. |
| Flow-through pinout | Input-to-output alignment simplifies layer stacking and reduces vias in high-speed routing. |

FAQ
What is the maximum clock frequency supported by CY74FCT162374ATPVC?
The CY74FCT162374ATPVC has a 6.5 ns maximum propagation delay and 5.0 ns minimum clock pulse width, supporting reliable operation up to approximately 150 MHz in well-terminated systems. Actual maximum frequency depends on board layout, load capacitance, and timing margins for setup/hold requirements.
Does CY74FCT162374ATPVC support hot-swap or partial-power-down operation?
Yes, CY74FCT162374ATPVC includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during hot-swap or partial-power-down conditions-fully specified per JEDEC standards for industrial applications.
What is the purpose of the dual OE and CLK inputs on CY74FCT162374ATPVC?
The CY74FCT162374ATPVC features separate 1OE/1CLK and 2OE/2CLK inputs to support two independent 8-bit register banks. This enables flexible configuration-either as two isolated 8-bit latches or as a unified 16-bit register when inputs are tied together.
Can CY74FCT162374ATPVC drive 50 Ω transmission lines directly?
Yes, CY74FCT162374ATPVC's ±24 mA balanced output drivers are designed to directly terminate 50 Ω lines with minimal overshoot/undershoot. Its integrated current-limiting resistors eliminate need for external series resistors in most point-to-point configurations.
Is CY74FCT162374ATPVC pin-compatible with CY74FCT16374ATPVC?
No, CY74FCT162374ATPVC and CY74FCT16374ATPVC share the same SSOP-48 package and pinout but differ electrically: the former uses 24 mA balanced drivers with lower ground bounce, while the latter provides 64 mA sink/32 mA source for heavy capacitive loads-functionally distinct drive profiles.
