Product details
Overview
74FCT16952CTPVG from Renesas Electronics is a 16-bit registered transceiver IC built in 0.5 µm CMOS, operating at 5 V with industrial temperature range (–40°C to +85°C), featuring ±32 mA/±64 mA drive strength, <250 ps output skew, and live-insertion support via power-off disable outputs.
For engineers reviewing the 74FCT16952CTPVG datasheet, 74FCT16952CTPVG pinout, 74FCT16952CTPVG application, or 74FCT16952CTPVG equivalent, this device serves as a high-speed, low-power ABT-compatible replacement for bidirectional data buffering in backplane and bus interface systems requiring precise timing control and robust drive capability.
Technical Context
The 74FCT16952CTPVG implements two independent 8-bit D-type registered transceivers with separate A-to-B and B-to-A control paths-each with dedicated clock enable (xCEAB/xCEBA), clock (xCLKAB/xCLKBA), and output enable (xOEAB/xOEBA) inputs. Data latching occurs on low-to-high clock transitions under active clock enable.
Its output buffers are designed for high-capacitance loads and low-impedance backplanes, with power-off disable ensuring safe live insertion. Input leakage ≤1 µA and output ground bounce <1.0 V (VCC = 5 V, TA = 25°C) support stable operation in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Voltage | 5.0 V ±10% - fixed single-supply operation compatible with legacy TTL/CMOS logic families |
| Propagation Delay (tPLH/tPHL) | Max 6.3 ns - enables reliable 100+ MHz bus operation with tight timing margins |
| Output Drive (IOH/IOL) | –32 mA / +64 mA - sufficient to drive 50 Ω transmission lines or 30+ pF loads without external buffers |
| Output Skew (tSK(o)) | ≤0.5 ns - ensures deterministic parallel data capture across all 16 bits in synchronous systems |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control, automation, and communications equipment |
| Input Leakage (IIH/IIL) | ±1 µA max - minimizes static current draw and prevents false triggering in high-impedance signal routing |
| Power-Off Leakage (IOFF) | ±1 µA at VCC = 0 V - guarantees safe hot-swap behavior without backfeeding or latch-up risk |
Pinout & Package
74FCT16952CTPVG is housed in a 56-pin Shrink Small Outline Package (SSOP), package code PVG56, with 0.635 mm lead pitch and JEDEC MO-153 compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A8, 2A1–2A8 | A-side data I/O (bidirectional) | 8-bit ports per register bank; function as inputs when enabled for A→B flow, outputs when enabled for B→A flow |
| 1B1–1B8, 2B1–2B8 | B-side data I/O (bidirectional) | 8-bit ports per register bank; complementary to A-side with independent control logic |
| xOEAB, xOEBA | Active-low output enable | Tri-states respective B or A port outputs; supports bus sharing and contention-free multiplexing |
| xCEAB, xCEBA | Active-low clock enable | Gates clock propagation to registers-prevents spurious latching during clock jitter or noise |
| xCLKAB, xCLKBA | Positive-edge clock inputs | Sample A or B port data on rising edge only when corresponding CE is asserted low |
| VCC, GND | Power supply terminals | Single 5 V supply with multiple VCC/GND pairs distributed across package for low-noise decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Live insertion support | Power-off disable outputs prevent backfeeding and enable hot-plug capability in modular backplane systems |
| Dual independent 8-bit banks | Enables asymmetric data flow control-e.g., A→B at 100 MHz while B→A remains idle or operates at different rate |
| Low-output skew (≤0.5 ns) | Guarantees simultaneous valid data on all 16 outputs, critical for parallel bus integrity and setup/hold compliance |
| High-drive CMOS outputs | –32 mA IOH / +64 mA IOL eliminates need for external line drivers in medium-length PCB traces or backplane stubs |
| Industrial temperature qualification | Validated operation from –40°C to +85°C ensures reliability in factory automation, telecom infrastructure, and transportation electronics |

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 |
|---|---|---|---|
| 74FCT16952ATPVG | Slower speed grade: 10 ns max tPLH vs. 6.3 ns for 74FCT16952CTPVG | Suitable for lower-frequency bus designs (<80 MHz) where timing margin is less constrained | Select when cost sensitivity outweighs need for maximum speed; identical pinout and DC specs |
| SN74ALVCH162245DGGR | 3.3 V only, no 5 V tolerance; different control architecture (non-clocked, direction-only) | Requires level translation for 5 V systems; lacks register functionality for synchronous capture | Choose only for new 3.3 V designs needing voltage translation and direction control-not for registered timing-critical paths |
Compared with 74FCT16952ATPVG and SN74ALVCH162245DGGR, the 74FCT16952CTPVG uniquely delivers 5 V compatibility, registered synchronous operation, and sub-7 ns timing-all in a drop-in SSOP-56 package-making it optimal for industrial backplane upgrades requiring ABT-equivalent performance.

FAQ
What is the maximum clock frequency supported by the 74FCT16952CTPVG?
The 74FCT16952CTPVG does not specify a maximum clock frequency in its datasheet; instead, it defines timing parameters such as tW (minimum pulse width) of 3 ns and tPLH/tPHL of up to 6.3 ns. Based on these values, reliable operation is achievable at clock frequencies up to approximately 100 MHz in well-designed PCB layouts with proper termination and decoupling. The 74FCT16952CTPVG is optimized for synchronous bus interfacing rather than continuous high-frequency toggling.
Does the 74FCT16952CTPVG support mixed-voltage operation (e.g., 3.3 V inputs with 5 V supply)?
No, the 74FCT16952CTPVG is a 5 V-only device. Its absolute maximum input voltage is VCC + 0.5 V (5.5 V), and VIH is specified at 2.0 V minimum-compatible with TTL and 5 V CMOS logic levels-but it is not 3.3 V tolerant. Applying 3.3 V signals directly is acceptable only if they meet the VIH/VIL thresholds; however, sustained 3.3 V inputs may degrade noise margin. For true mixed-voltage systems, level-shifting circuitry is required before the 74FCT16952CTPVG inputs.
Can the 74FCT16952CTPVG be used without connecting all VCC and GND pins?
No. The 74FCT16952CTPVG has multiple dedicated VCC and GND pins distributed across the 56-pin SSOP package (e.g., pins 6, 11, 20, 25, 32, 41, 46, 51) to minimize power delivery impedance and reduce ground bounce. Omitting any VCC or GND connection violates the recommended layout and risks increased switching noise, timing violations, or latch-up. All VCC and GND pins must be properly decoupled and connected per the manufacturer's layout guidelines for the 74FCT16952CTPVG.
Is the 74FCT16952CTPVG pin-compatible with other members of the FCT16952 family?
Yes-the 74FCT16952CTPVG shares identical pinout and package (PVG56 SSOP-56) with all speed grades (A, C, E) and package variants (PAG/TSSOP and PVG/SSOP) of the FCT16952 series. Electrical differences are limited to AC timing (e.g., tPLH, tPHL) and certain DC parameters like ICC; no pin function or assignment changes exist across variants. This allows direct substitution within the same package type, provided timing requirements are met for the 74FCT16952CTPVG.
What does "power-off disable" mean for the 74FCT16952CTPVG outputs?
"Power-off disable" means that when VCC = 0 V, the 74FCT16952CTPVG outputs enter a high-impedance state regardless of input or control pin states-preventing back-driving of powered circuitry during live insertion or removal. This feature is enabled by internal circuitry that detects VCC loss and forces output transistors into cutoff. It is verified by IOFF ≤ ±1 µA at VCC = 0 V and VIN/VO ≤ 4.5 V, making the 74FCT16952CTPVG safe for hot-swap backplane applications.
