Product details
Overview
CY74FCT16952ETPVC from Texas Instruments is a 16-bit registered transceiver IC designed for bidirectional data flow between two buses with independent A-to-B and B-to-A control paths. It features 64 mA sink / 32 mA source drive capability, typical output skew <250 ps, and operates at VCC = 5V ±10% across –40°C to +85°C for industrial backplane and high-capacitance load interfacing.
For engineers reviewing the CY74FCT16952ETPVC datasheet, CY74FCT16952ETPVC pinout, CY74FCT16952ETPVC application, or CY74FCT16952ETPVC equivalent, key selection criteria include its dual-clock-register architecture, Ioff partial-power-down support, edge-rate-controlled outputs for noise reduction, and SSOP-56 package compatibility with legacy 300-mil pitch layouts.
Technical Context
This device integrates two synchronized 8-bit registered transceivers sharing common control lines (CEAB/CEBA, CLKAB/CLKBA, OEAB/OEBA) to achieve full 16-bit operation. Its register-based architecture latches input data on clock edges and enables three-state outputs via separate active-low output enables per direction.
The CY74FCT16952ETPVC implements Ioff circuitry to disable outputs during power-down, preventing current backflow, and uses edge-rate control to suppress ground bounce-typical VOLP <1.0 V at VCC = 5 V and TA = 25°C-making it suitable for driving low-impedance backplanes without external termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - fixed single-rail operation compatible with legacy TTL/CMOS 5-V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit registered transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16952ATPVC | Slower 10.0 ns max propagation delay vs. CY74FCT16952ETPVC's 10.0 ns (same spec bin); identical drive strength and pinout | Same industrial temperature range and SSOP-56 package; suitable where timing margin exceeds 10 ns | Select for cost-sensitive designs where full speed is not required; verified drop-in replacement in existing layouts |
| CY74FCT162952BTPVC | 24 mA balanced drive (vs. 64/32 mA asymmetrical), lower VOLP (<0.6 V), no Ioff support | Optimized for transmission-line driving with reduced ground bounce; lacks partial-power-down capability | Prefer when driving controlled-impedance traces; avoid if system requires hot-swap or mixed-supply isolation |
Compared with CY74FCT16952ATPVC, the CY74FCT16952ETPVC offers identical timing specs but is marked as obsolete per TI documentation-CY74FCT16952ATPVC remains ACTIVE and recommended. Versus CY74FCT162952BTPVC, CY74FCT16952ETPVC delivers higher sink current for backplane loads but lacks bus-hold and balanced drive, making it less suitable for floating-input or low-noise line-driving use cases.

FAQ
What is the operating voltage range for CY74FCT16952ETPVC?
CY74FCT16952ETPVC operates at VCC = 5 V ±10%, meaning 4.5 V to 5.5 V. This fixed single-supply requirement aligns with legacy TTL-compatible systems and ensures consistent drive strength and timing performance across the specified industrial temperature range of –40°C to +85°C. The device does not support dual-supply or wide-VCC operation.
Does CY74FCT16952ETPVC support partial-power-down mode?
Yes, CY74FCT16952ETPVC includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow in partially powered systems. This feature is explicitly documented in the datasheet and enables safe hot-swap operation and mixed-voltage domain interfacing-critical for modular industrial controllers where subsystems power up/down independently.
What package type and dimensions does CY74FCT16952ETPVC use?
CY74FCT16952ETPVC uses a 56-pin SSOP (Shrunk Small Outline Package), designated O56, with 300-mil body width and 0.025-inch pitch. Mechanical dimensions are 18.54 mm × 7.59 mm × 2.39 mm max height, compliant with JEDEC MO-118. This package is distinct from TSSOP variants (e.g., DGG) and shares footprint compatibility with other CY74FCT16xxx SSOP devices.
How does CY74FCT16952ETPVC handle ground bounce?
CY74FCT16952ETPVC incorporates edge-rate control circuitry that limits output slew rate, resulting in typical ground bounce (VOLP) <1.0 V at VCC = 5 V and TA = 25°C. This design significantly reduces simultaneous switching noise compared to standard FCT devices, enabling direct connection to high-capacitance backplanes without external damping resistors or layout mitigation.
Is CY74FCT16952ETPVC pin-compatible with other members of the CY74FCT16xxx family?
Yes, CY74FCT16952ETPVC shares identical pinout and package (SSOP-56) with CY74FCT16952ATPVC and CY74FCT16952CTPACT, differing only in speed grade and marking. All variants use the same functional pin mapping-including OEAB/OEBA, CEAB/CEBA, CLKAB/CLKBA, and bidirectional A/B I/O banks-enabling direct substitution in existing layouts where timing and drive requirements align.
