Product details
Overview
FCT162652CTPVCTG4 from Texas Instruments is a 16-bit registered transceiver organized as two independent 8-bit bus transceivers with three-state D-type registers, 5.4 ns bus-to-bus propagation delay, 24 mA balanced output drivers, and Ioff support for partial-power-down mode operation. It operates at VCC = 5V ±10% across −40°C to +85°C and is used in high-speed backplane and transmission-line interfacing.
For engineers reviewing the FCT162652CTPVCTG4 datasheet, FCT162652CTPVCTG4 pinout, FCT162652CTPVCTG4 application, or FCT162652CTPVCTG4 equivalent, key selection criteria include output drive balance (24 mA), ground bounce performance (<0.6 V), real-time/stored data multiplexing capability, and TSSOP-56 packaging compatibility with industrial temperature requirements.
Technical Context
This device implements dual 8-bit registered transceiver logic with separate CLKAB/CLKBA clocks and SAB/SBA select controls, enabling concurrent or staggered loading of A- and B-bus data into internal D flip-flops. Its edge-rate control circuitry reduces system switching noise and improves signal integrity on high-capacitance buses.
The Ioff feature disables outputs during power-down to prevent current backflow, while balanced 24 mA drivers with integrated current-limiting resistors minimize undershoot and eliminate need for external termination on transmission lines. Output skew is guaranteed ≤0.5 ns across all pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 5 V ±10% - Ensures stable operation across industrial supply variations without regulation overhead. |
| Propagation Delay (Bus-to-Bus) | 1.5–5.4 ns - Enables sub-6 ns timing-critical data transfers between parallel buses. |
| Output Drive (IOH/IOL) | ±24 mA - Balanced sourcing/sinking supports clean signal edges on 50-Ω transmission lines. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - Reduces noise coupling into shared ground planes. |
| Operating Temperature | −40°C to +85°C - Qualified for industrial-grade embedded and communications equipment. |
| Ioff Support | Active at VCC = 0 V - Prevents damaging back-current when powered down in mixed-voltage systems. |

Key Features
| Feature | Design Value |
|---|---|
| Balanced 24 mA output drivers | Eliminates need for external series termination on 50-Ω traces and reduces ground bounce-induced jitter. |
| Edge-rate control circuitry | Controls slew rate to suppress harmonic content above 100 MHz, improving EMC compliance in dense layouts. |
| Ioff partial-power-down support | Prevents backflow current when VCC = 0 V, enabling safe hot-insertion and multi-rail power sequencing. |
| Typical output skew < 0.5 ns | Ensures deterministic timing alignment across all 16 outputs-critical for synchronous bus capture. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar registered transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16652CTPVCT | Higher drive (64 mA sink / 32 mA source); no current-limiting resistors; higher ground bounce (VOLP <1.0 V). | Better suited for driving heavy capacitive loads (>100 pF) but requires external termination and careful layout for noise control. | Select when maximum fanout to unterminated stubs is required and ground bounce is mitigated by layout. |
| SN74ALVCH162652GR | 3.3 V only (1.65–3.6 V), lower drive (±24 mA), same pin count but different pinout; no Ioff support. | Designed for low-voltage LVTTL systems; incompatible with 5 V buses and lacks power-down safety for mixed-rail designs. | Choose only for new 3.3 V-only architectures where legacy 5 V interoperability is not needed. |
Compared with CY74FCT16652CTPVCT and SN74ALVCH162652GR, FCT162652CTPVCTG4 uniquely combines 5 V operation, Ioff protection, and integrated current-limiting for transmission-line use-making it optimal for industrial backplanes requiring robustness and layout simplicity.

FAQ
What is the maximum clock frequency supported by FCT162652CTPVCTG4?
FCT162652CTPVCTG4 does not specify a maximum clock frequency in its datasheet; instead, it guarantees timing parameters including 5.4 ns bus-to-bus propagation delay and 5.0 ns minimum clock pulse width. System-level maximum toggle rate depends on layout, load, and timing margins-but with 5.4 ns delay and 2.0 ns setup time, reliable operation up to 100 MHz is achievable in well-designed PCB environments using FCT162652CTPVCTG4.
Does FCT162652CTPVCTG4 support hot-swap or partial-power-down operation?
Yes, FCT162652CTPVCTG4 includes Ioff circuitry that actively disables outputs when VCC = 0 V, preventing damaging current backflow during hot-swap events or power sequencing mismatches. This feature is fully characterized and specified in the datasheet, making FCT162652CTPVCTG4 suitable for mixed-voltage systems where subsystems power up/down independently.
What package type and dimensions does FCT162652CTPVCTG4 use?
FCT162652CTPVCTG4 uses a 56-pin TSSOP (Thin Shrunk Small Outline Package), designated DGG by Texas Instruments, with 0.5 mm lead pitch, 13.9 mm × 6.1 mm body size, and 1.2 mm maximum height. It complies with JEDEC MO-153 and is compatible with standard SMT reflow profiles for lead-free assembly.
How does FCT162652CTPVCTG4 differ from CY74FCT16652T in output driver design?
FCT162652CTPVCTG4 features balanced ±24 mA output drivers with integrated current-limiting resistors, minimizing ground bounce (<0.6 V) and eliminating external termination. In contrast, CY74FCT16652T provides asymmetric 64 mA sink / 32 mA source drive without built-in resistors-requiring external termination and exhibiting higher ground bounce (<1.0 V)-making FCT162652CTPVCTG4 preferable for transmission-line applications.
Can FCT162652CTPVCTG4 operate with 3.3 V logic levels?
No, FCT162652CTPVCTG4 is a 5 V-only device specified for VCC = 5 V ±10% (4.5 V to 5.5 V). Its input thresholds (VIH = 2.0 V, VIL = 0.8 V) and output drive characteristics are designed for TTL-compatible signaling. Interfacing with 3.3 V systems requires level-shifting; direct connection may result in unreliable logic thresholds or excessive input current outside specification limits for FCT162652CTPVCTG4.
