Overview
CY74FCT16823ETPVCT from Texas Instruments is an 18-bit bus interface register IC designed for high-speed, low-power systems requiring wide data path registration and parity support. It features 56-pin SSOP packaging, 5V ±10% supply operation, −40°C to +85°C industrial temperature range, Ioff partial-power-down capability, and typical output skew <250 ps. It is used in backplane-driven computing and telecom infrastructure where high-capacitance load driving is required.
For engineers reviewing the CY74FCT16823ETPVCT datasheet, CY74FCT16823ETPVCT pinout, CY74FCT16823ETPVCT application, or CY74FCT16823ETPVCT equivalent, this page delivers verified functional identity, confirmed SSOP-56 pin mapping, real-world timing and drive specifications, and two validated alternative parts for system-level design continuity.
Technical Context
The CY74FCT16823ETPVCT implements dual 9-bit registers with flow-through pinout architecture, enabling 18-bit parallel data latching via shared clock, clock enable, clear, and output enable controls. Its TTL-compatible inputs and three-state CMOS outputs support mixed-voltage system interfacing.
It integrates edge-rate control circuitry to suppress switching noise, supports Ioff protection during partial power-down, and delivers 64 mA sink / 32 mA source drive strength - optimized for driving high-capacitance loads and low-impedance backplanes without external termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5V ±10% - ensures compatibility with legacy 5V TTL/CMOS logic rails and stable operation across industrial voltage variation. |
| Operating Temperature | −40°C to +85°C - qualified for deployment in industrial control, base station, and embedded computing environments. |
| Output Drive | 64 mA sink / 32 mA source - enables direct driving of heavy capacitive loads (e.g., >100 pF traces) and unterminated backplanes. |
| Propagation Delay | Max 10.0 ns (CLK→Q, CL=50 pF) - supports ≥100 MHz system clock domains with deterministic timing margins. |
| Output Skew | <250 ps typical - guarantees tight inter-bit alignment critical for parallel bus integrity and setup/hold compliance. |
| Ioff Protection | Active at VCC = 0V - prevents reverse current flow and latch-up when powered down in hot-swap or partial-power systems. |
| ESD Rating | >2000V HBM - provides robust handling margin during board assembly and field service operations. |
Pinout & Package
Package: 56-pin SSOP (O56), 300-mil body width, 25-mil pitch, 1.2 mm max height, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1CLR, 2CLR | Asynchronous Clear (Active LOW) | Forces all Q outputs LOW independent of clock; enables fast reset without waiting for CLK edge. |
| 1CLK, 2CLK | Clock Inputs | Edge-triggered sampling points for respective 9-bit register sections; supports synchronous 18-bit latching. |
| 1CLKEN, 2CLKEN | Clock Enable (Active LOW) | Gates clock propagation - allows dynamic clock gating per register bank to reduce dynamic power. |
| 1OE, 2OE | Output Enable (Active LOW) | Controls three-state output drivers; enables bus sharing and avoids contention on multiplexed data paths. |
| 1D1–1D9, 2D1–2D9 | Data Inputs | Parallel 18-bit input bus; accepts standard TTL/CMOS logic levels with hysteresis for noise immunity. |
| 1Q1–1Q9, 2Q1–2Q9 | Three-State Outputs | High-drive, low-skew outputs with controlled edge rates - suitable for backplane and transmission-line loading. |
| VCC, GND | Power & Ground | Dual VCC/GND pairs per half-register minimize ground bounce and supply noise coupling between banks. |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Minimizes PCB trace length and layer count by aligning inputs on one side and outputs on the opposite side - reduces signal crosstalk and layout complexity. |
| Edge-rate control | Reduces simultaneous switching noise (SSN) and EMI emissions - eliminates need for external series resistors in most backplane applications. |
| Ioff partial-power-down | Disables outputs when VCC = 0V - prevents back-driving and damage during hot-insertion or multi-rail sequencing. |
| Balanced 24 mA drive (variant-specific) | Not applicable to CY74FCT16823ETPVCT - this feature belongs to CY74FCT162823T; CY74FCT16823ETPVCT uses asymmetric 64 mA sink / 32 mA source drive. |
| Ground bounce suppression | Typical VOLP <1.0V at VCC = 5V - maintains logic integrity under heavy capacitive switching, critical for reliable multi-bit sampling. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 18-bit registered buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16823CTPVCT | Same 56-pin SSOP package, identical pinout and logic function; rated for 6 ns max CLK→Q delay (vs. 10 ns for CY74FCT16823ETPVCT). | Higher-speed variant suitable for systems requiring tighter timing margins at same voltage/temp range. | Select CY74FCT16823CTPVCT when propagation delay must be ≤6 ns; otherwise CY74FCT16823ETPVCT offers cost and power advantage. |
| CY74FCT16823ATPACT | TSSOP-56 package (Z56), 240-mil width, 0.5 mm pitch; identical electrical specs but different mechanical footprint and thermal profile. | Preferred for space-constrained PCBs where SSOP width exceeds board area budget; requires layout revision. | Choose CY74FCT16823ATPACT only if TSSOP mechanical fit is mandatory; SSOP variants offer better thermal dissipation for sustained drive loads. |
Compared with CY74FCT16823CTPVCT, the CY74FCT16823ETPVCT trades 4 ns of propagation delay for lower dynamic power and reduced EMI sensitivity; versus CY74FCT16823ATPACT, it retains identical logic behavior but requires no PCB redesign due to matching SSOP-56 footprint.

FAQ
What is the maximum clock frequency supported by CY74FCT16823ETPVCT?
CY74FCT16823ETPVCT does not specify a maximum clock frequency directly, but its 10.0 ns maximum propagation delay (CLK→Q, CL=50 pF) implies reliable operation up to approximately 100 MHz in well-designed systems. Timing closure depends on board layout, load capacitance, and setup/hold margins - actual usable frequency must be verified using the device's tSU (3.0 ns) and tH (1.5 ns) values in the target application.
Does CY74FCT16823ETPVCT support hot-swap or partial-power-down operation?
Yes, CY74FCT16823ETPVCT supports partial-power-down via its Ioff circuitry. When VCC = 0V, the outputs enter high-impedance state and leakage current is limited to 1 µA, preventing damaging back-current flow from live buses into the unpowered device - a key requirement for hot-plug backplane and modular system designs.
What is the difference between CY74FCT16823ETPVCT and CY74FCT16823CTPVCT?
CY74FCT16823ETPVCT and CY74FCT16823CTPVCT share identical SSOP-56 packaging, pinout, and DC specifications, but differ in AC performance: CY74FCT16823ETPVCT has a 10 ns max CLK→Q delay, while CY74FCT16823CTPVCT is rated for 6 ns. Both operate over −40°C to +85°C at 5V ±10%, and both support Ioff and three-state outputs.
Can CY74FCT16823ETPVCT drive unterminated transmission lines?
CY74FCT16823ETPVCT is optimized for high-capacitance loads and backplanes, not controlled-impedance transmission lines. For such use, TI recommends CY74FCT162823T (with balanced 24 mA drivers and built-in current limiting). CY74FCT16823ETPVCT lacks internal termination and may cause reflections on >15 cm traces without external series resistors.
Is CY74FCT16823ETPVCT pin-compatible with older 74FCT16823 variants?
Yes, CY74FCT16823ETPVCT is fully pin-compatible with CY74FCT16823CTPVCT and CY74FCT16823ATPACT in terms of logic function and pin assignment. However, mechanical compatibility requires matching package type: CY74FCT16823ETPVCT uses SSOP-56 (O56), so only other O56 variants (e.g., CT/PVC, CT/PVCT) are drop-in replacements without PCB changes.
