Product details
Overview
CY74FCT16245TPVCT from Texas Instruments is a 16-bit non-inverting bus transceiver designed for bidirectional synchronous communication between two 16-bit buses in high-speed digital systems. It features 64 mA sink / 32 mA source drive capability, 7.0 ns max propagation delay (A↔B), and Ioff partial-power-down support. It is used in industrial backplane interfaces requiring robust noise immunity and high-capacitance load driving.
For engineers reviewing the CY74FCT16245TPVCT datasheet, CY74FCT16245TPVCT pinout, CY74FCT16245TPVCT application, or CY74FCT16245TPVCT equivalent, key selection criteria include its 48-pin SSOP package, 5V ±10% supply, industrial temperature range (–40°C to +85°C), and directional control via DIR/OE pins with three-state outputs.
Technical Context
The CY74FCT16245TPVCT implements dual 8-bit transceiver blocks (1A/1B and 2A/2B) with independent direction (DIR) and output enable (OE) controls per block. Data flow is bidirectional: when DIR = LOW, data transfers from B to A; when DIR = HIGH, data flows from A to B. OE = LOW enables outputs; OE = HIGH places all outputs in high-impedance state.
It uses FCT logic family silicon with edge-rate control circuitry to minimize switching noise and ground bounce (<1.0 V typical VOLP at VCC = 5 V). The device supports Ioff protection, disabling outputs and blocking current backflow during partial power-down, and operates across –40°C to +85°C with VCC = 5 V ±10%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - compatible with standard TTL/CMOS 5-V systems; no level-shifting required. |
| Propagation Delay | 7.0 ns max (A↔B) - enables reliable operation in 140+ MHz bus systems with timing margin. |
| Output Drive | 64 mA sink / 32 mA source - drives heavy capacitive loads (e.g., backplanes, long traces) without external buffers. |
| Ground Bounce (VOLP) | <1.0 V typical at VCC = 5 V, TA = 25°C - reduces signal integrity risk in dense PCB layouts. |
| Ioff Support | Active at VCC = 0 V - prevents damaging back-current during hot-insertion or partial system power-down. |
| ESD Rating | >2000 V HBM - enhances reliability in handling and manufacturing environments. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and control applications. |
Pinout & Package
Package: 48-pin SSOP (O48), 300-mil body width, 0.025-inch pitch, 1.2 mm max height. RoHS-compliant, moisture sensitivity level (MSL) per JEDEC MO-153.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control inputs (per 8-bit bank) | Set data flow direction: LOW = B→A, HIGH = A→B; asynchronous control with no internal latching. |
| 1OE, 2OE | Three-state output enable (active LOW) | Enable/disable respective 8-bit output banks; HIGH forces high-impedance isolation between buses. |
| 1A1–1A8, 2A1–2A8 | Port A I/O terminals | Bidirectional data lines for first and second 8-bit bus segments; function as inputs or three-state outputs based on DIR/OE. |
| 1B1–1B8, 2B1–2B8 | Port B I/O terminals | Complementary bidirectional data lines; paired with Port A under shared DIR/OE control per bank. |
| VCC (Pins 24, 25, 47, 48) | Power supply | Four dedicated VCC pins reduce IR drop and improve noise rejection across the 48-pin layout. |
| GND (Pins 12, 13, 26, 27, 39, 40) | Ground reference | Six GND pins provide low-inductance return paths, critical for minimizing ground bounce in high-drive operation. |
Key Features
| Feature | Design Value |
|---|---|
| Edge-rate controlled outputs | Reduces simultaneous switching noise (SSN) and EMI by limiting slew rate without sacrificing speed. |
| Typical output skew <250 ps | Ensures tight timing alignment across all 16 outputs-critical for parallel bus setup/hold compliance. |
| 64 mA sink capability | Directly drives terminated transmission lines or high-C loads (e.g., >100 pF) without external drivers. |
| Ioff partial-power-down | Allows safe insertion/removal in live backplanes; blocks reverse current when VCC = 0 V. |
| Industrial temperature range | Validated operation from –40°C to +85°C ensures reliability in factory automation and outdoor control cabinets. |
Applications
| Industrial Backplane Interface | Memory Expansion Subsystem |
|---|---|
|

IC Role / Device Role / Timing Role: Directional data bridge enabling read/write arbitration between FPGA fabric and external memory ports. Use Value: Independent DIR/OE per 8-bit bank allows fine-grained control of memory access windows; Ioff prevents data corruption during FPGA reconfiguration. |
| Programmable Logic I/O Expansion | Legacy Bus Protocol Adapter |
|
Use Scenario: Interfacing a modern microcontroller GPIO bank to legacy 16-bit parallel peripherals (e.g., printers, scanners) requiring TTL-level signaling. IC Role / Device Role / Timing Role: Voltage- and timing-compatible bus buffer translating between MCU-native logic and legacy peripheral timing envelopes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT162245TPVCT | 24 mA balanced drive (sink/source), lower ground bounce (<0.6 V), no high-drive sink capability | Better suited for transmission-line driving with termination; less ideal for high-C backplanes | Select when signal integrity on matched-impedance lines is prioritized over raw drive strength. |
| CY74FCT162H245TPVCT | Includes bus-hold inputs (no external pull-ups), same 24 mA drive, eliminates floating-input risk | Preferred in systems with intermittent bus activity or unconnected stubs where input stability is critical | Choose when input conditioning is needed and high sink current is not required. |
Compared with CY74FCT162245TPVCT and CY74FCT162H245TPVCT, the CY74FCT16245TPVCT provides superior drive strength for backplane loading but lacks bus-hold and balanced drive optimization-making it the optimal choice for high-capacitance, high-noise industrial interconnects where raw current delivery is decisive.

FAQ
What is the maximum operating frequency supported by the CY74FCT16245TPVCT?
The CY74FCT16245TPVCT does not specify a maximum clock frequency directly, but its 7.0 ns maximum propagation delay (A↔B) supports reliable operation in synchronous bus systems up to approximately 140 MHz, assuming adequate setup/hold margins. Actual achievable frequency depends on PCB layout, load capacitance, and system-level timing constraints-not internal clocking.
Does the CY74FCT16245TPVCT support 3.3 V logic levels?
No, the CY74FCT16245TPVCT is a 5 V-only device specified for VCC = 5 V ±10%. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) are TTL-compatible but not optimized for 3.3 V signaling. Driving it from 3.3 V sources may result in marginal noise margins; level translation is recommended for mixed-voltage systems.
How many power and ground pins does the CY74FCT16245TPVCT have in its SSOP package?
The CY74FCT16245TPVCT in the 48-pin SSOP (O48) package has four VCC pins (pins 24, 25, 47, 48) and six GND pins (pins 12, 13, 26, 27, 39, 40). This distributed power/ground architecture minimizes voltage drop and improves noise immunity in high-drive operation.
Can the CY74FCT16245TPVCT be used in partial-power-down mode?
Yes, the CY74FCT16245TPVCT includes Ioff circuitry that disables outputs and blocks reverse current when VCC = 0 V. This allows safe use in hot-swap or modular backplane applications where sections of the system may be powered down independently without damaging the device or corrupting adjacent bus signals.
What is the purpose of separate DIR and OE pins on the CY74FCT16245TPVCT?
The CY74FCT16245TPVCT uses independent DIR (direction) and OE (output enable) pins per 8-bit bank to provide granular control: DIR selects data flow direction (A↔B), while OE enables/disables output drivers. This allows bidirectional data transfer with precise timing isolation-e.g., holding outputs in high-Z during direction changes to prevent bus contention.
