Product details
Overview
CY74FCT162652ATPVC from Texas Instruments is a 16-bit registered transceiver organized as two independent 8-bit bus transceivers with three-state D-type registers, 5V ±10% supply, 6.3 ns max propagation delay (bus-to-bus), 24 mA balanced output drive, and industrial temperature range (−40°C to +85°C); used for bidirectional data routing in high-speed backplane and transmission-line interfaces.
For engineers reviewing the CY74FCT162652ATPVC datasheet, CY74FCT162652ATPVC pinout, CY74FCT162652ATPVC application, or CY74FCT162652ATPVC equivalent, this page delivers verified functional architecture, real-time vs. stored-data transfer modes, Ioff partial-power-down support, ground-bounce-optimized driver design, and SSOP-56 package integration details.
Technical Context
The CY74FCT162652ATPVC implements dual 8-bit registered transceiver logic with separate CLKAB/CLKBA clocks, SAB/SBA data-source select inputs, and OEAB/OEBA three-state enables - enabling simultaneous or staggered storage of A- or B-bus data into internal D flip-flops. Its architecture supports both real-time pass-through and registered hold modes without external latching.
It features edge-rate controlled outputs with typical VOLP < 0.6 V at VCC = 5 V and TA = 25°C, 24 mA balanced sink/source drivers with integrated current-limiting resistors, and Ioff circuitry that disables outputs during power-down to prevent backflow current - critical for hot-swap and mixed-voltage system designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10%; ensures compatibility with legacy 5V TTL/CMOS systems and stable operation across industrial voltage variation. |
| Propagation Delay (Bus-to-Bus) | 6.3 ns max; enables reliable timing closure in high-speed parallel bus applications up to ~80 MHz effective throughput. |
| Output Drive Strength | ±24 mA balanced; reduces need for external termination, minimizes undershoot, and supports direct driving of 50-Ω transmission lines. |
| Ground Bounce (VOLP) | <0.6 V typical at VCC = 5 V, TA = 25°C; lowers noise coupling into shared ground planes and improves signal integrity in dense PCB layouts. |
| Operating Temperature | −40°C to +85°C; qualified for industrial environments including factory automation, telecom infrastructure, and embedded control systems. |
| Ioff Support | Active at VCC = 0 V; prevents damaging current flow when powered down while other system rails remain active - essential for partial-power-down architectures. |
| Input Hysteresis | 100 mV; increases noise immunity on control inputs (OEAB, SAB, etc.) in electrically noisy industrial settings. |
Pinout & Package
Package: 56-pin SSOP (O56), 300-mil body width, 25-mil pitch, 1.2 mm max height - compatible with standard surface-mount assembly processes and IPC-7351 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OEAB, 2OEAB, 1OEBA, 2OEBA | Three-State Output Enable Inputs | Active-low controls for A→B and B→A direction outputs; allows independent bus isolation per 8-bit segment. |
| 1CLKAB, 2CLKAB, 1CLKBA, 2CLKBA | Register Clock Inputs | LOW-to-HIGH transitions latch data from A or B bus into internal D flip-flops - independent of OE/S state. |
| 1SAB, 2SAB, 1SBA, 2SBA | Data Source Select Inputs | Selects real-time (S = L) or stored-register (S = H) data for output - enables flexible multiplexed bus arbitration. |
| 1A1–1A8, 2A1–2A8 | A-Bus Data Inputs / Outputs | Bi-directional I/O pins for first and second 8-bit A-side channels; function as inputs when OEBA active, outputs when OEAB active. |
| 1B1–1B8, 2B1–2B8 | B-Bus Data Inputs / Outputs | Bi-directional I/O pins for first and second 8-bit B-side channels; function as inputs when OEAB active, outputs when OEBA active. |
| VCC, GND (multiple pins) | Power and Ground Distribution | Multiple dedicated VCC/GND pins minimize IR drop and ground bounce across 16-bit switching activity. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24 mA output drivers | Reduces external termination requirements and suppresses transmission-line reflections in point-to-point or stubbed bus topologies. |
| Edge-rate controlled outputs | Minimizes EMI generation and crosstalk in high-density routing, especially critical for mixed-signal PCBs with sensitive analog sections. |
| Ioff partial-power-down support | Enables safe insertion/removal in live backplanes and supports hierarchical power management without bus contention. |
| Typical output skew < 250 ps | Ensures deterministic timing alignment across all 16 bits - vital for synchronous parallel data capture in FPGA or ASIC interfaces. |
| ESD rating > 2000 V (HBM) | Provides robust handling margin during board assembly and field maintenance in uncontrolled electrostatic environments. |

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 |
|---|---|---|---|
| CY74FCT162652CTPVC | 5.4 ns max propagation delay (vs. 6.3 ns); otherwise identical electrical specs and pinout. | Suitable where tighter timing margins are required in high-frequency bus cycles (e.g., >100 MHz effective clock rate). | Select CTPVC for speed-critical designs; ATPVC remains optimal for cost-sensitive industrial applications with relaxed timing. |
| SN74FCT162652CPAG | TSSOP-56 (Z56) package, 240-mil width, 19.6-mil pitch; same AC/DC specs but different thermal and mechanical footprint. | Better suited for space-constrained layouts requiring finer-pitch assembly and lower profile (1.2 mm max height). | Choose PVCT/PVC variants for legacy SSOP tooling compatibility; PAG for newer compact designs with TSSOP reflow profiles. |
Compared with CY74FCT162652CTPVC and SN74FCT162652CPAG, the CY74FCT162652ATPVC offers the best balance of timing margin, thermal robustness in SSOP packaging, and industrial qualification - making it ideal for volume production where layout stability and supply chain continuity outweigh marginal speed gains or package miniaturization.

FAQ
What is the maximum clock frequency supported by CY74FCT162652ATPVC?
The CY74FCT162652ATPVC does not specify a maximum clock frequency directly, but its 6.3 ns max propagation delay (bus-to-bus) and 5.0 ns minimum clock pulse width imply reliable operation up to approximately 80 MHz for register-to-register transfers. System-level timing must account for setup/hold (tSU = 2.0 ns, tH = 1.5 ns) and board trace delays - actual usable frequency depends on PCB layout and load capacitance.
Does CY74FCT162652ATPVC support hot-swap or partial-power-down operation?
Yes, CY74FCT162652ATPVC includes Ioff circuitry that actively disables outputs when VCC = 0 V, preventing damaging current backflow from live buses into the unpowered device. This makes CY74FCT162652ATPVC suitable for hot-plug backplane applications and systems implementing staged power sequencing.
What is the difference between CY74FCT162652ATPVC and CY74FCT162652CTPVC?
The primary difference is speed grade: CY74FCT162652ATPVC has 6.3 ns max propagation delay, while CY74FCT162652CTPVC is faster at 5.4 ns. Both share identical pinout, DC specs, package (SSOP-56), and functional behavior. The 'A' suffix denotes the standard-speed variant optimized for cost and thermal performance in industrial applications.
Can CY74FCT162652ATPVC drive unterminated 50-Ω transmission lines?
Yes - CY74FCT162652ATPVC's ±24 mA balanced drivers and integrated current-limiting resistors allow direct driving of 50-Ω lines with minimal overshoot/undershoot. Measured VOLP < 0.6 V confirms low ground bounce, making it suitable for point-to-point or short-stub transmission-line topologies without external series termination.
Is CY74FCT162652ATPVC RoHS compliant?
Yes, CY74FCT162652ATPVC meets RoHS Directive 2011/65/EU requirements. As confirmed in TI's packaging documentation, the SSOP-56 package uses lead-free finish and complies with JEDEC J-STD-020 moisture sensitivity level (MSL) standards for surface-mount assembly.
