Product details

Overview

CY74FCT16245CTPACT from Texas Instruments is a 16-bit non-inverting bus transceiver with direction control (DIR) and three-state output enable (OE), designed for bidirectional synchronous communication between two 16-bit buses. It delivers 64 mA sink / 32 mA source drive strength, supports partial-power-down via I_off, operates at 5V ±10%, and achieves 4.1 ns max propagation delay (A↔B) over –40°C to +85°C - ideal for high-capacitance backplane driving in industrial control systems.

For engineers reviewing the CY74FCT16245CTPACT datasheet, CY74FCT16245CTPACT pinout, CY74FCT16245CTPACT application, or CY74FCT16245CTPACT equivalent, key selection criteria include its 48-pin TSSOP package, 64 mA sink capability, ground-bounce performance (<1.0 V VOLP), I_off-enabled power-down safety, and compatibility with TTL/CMOS logic levels in noise-sensitive 5V bus interface designs.

Technical Context

This device implements dual 8-bit transceiver blocks (1A/1B and 2A/2B), each controlled independently by dedicated DIR and OE pins. Data flow direction is determined solely by DIR state: LOW enables B→A transfer, HIGH enables A→B transfer. Outputs enter high-impedance state when OE is HIGH, isolating both buses.

The CY74FCT16245CTPACT uses FCT logic family architecture with edge-rate-controlled outputs to minimize switching noise and ground bounce. Its I_off circuitry actively disables outputs during V_CC = 0 V, preventing backflow current - critical for hot-swap and partial-power-down system architectures.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC	5 V ±10% - compatible with standard 5V TTL/CMOS systems without level-shifting.
Propagation Delay (t_PLH/t_PHL)	Max 4.1 ns (A↔B) - enables reliable operation in high-speed 16-bit data paths up to ~200 MHz clock-equivalent rates.
Output Drive	64 mA sink / 32 mA source - sufficient to drive heavy capacitive loads (e.g., >100 pF traces or backplanes) without external buffers.
V_OLP (Ground Bounce)	<1.0 V at V_CC = 5 V, T_A = 25°C - reduces signal integrity risk during simultaneous switching.
I_off	±1 µA at V_CC = 0 V - prevents damaging current flow during partial power-down or hot-insertion scenarios.
Operating Temperature	–40°C to +85°C - qualified for industrial-grade embedded systems including PLCs and motor drives.
ESD Rating	>2000 V HBM - enhances robustness against handling and board-level electrostatic discharge events.

Pinout & Package

Package: 48-pin TSSOP (DGG), 240-mil body width, 0.5 mm pitch, 1.2 mm max height - optimized for high-density PCB layouts with automated assembly compatibility.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction Control Inputs	Active-HIGH logic selects A→B data flow; LOW selects B→A - enables independent bidirectional control per 8-bit segment.
1OE, 2OE	Output Enable Inputs	Active-LOW enables outputs; HIGH places all associated A/B pins in high-impedance - allows dynamic bus isolation.
1A1–1A8, 2A1–2A8	Port A I/O Terminals	Bi-directional data terminals for first and second 8-bit bus segments - electrically identical to Port B for full 16-bit symmetry.
1B1–1B8, 2B1–2B8	Port B I/O Terminals	Bi-directional data terminals mirroring Port A - supports true dual-octal or unified 16-bit transceiver configuration.
V_CC (Pins 24, 25, 47, 48)	Power Supply	Four dedicated V_CC pins reduce supply impedance and improve noise immunity across wide bus widths.
GND (Pins 1, 2, 13, 14, 26, 27, 38, 39)	Ground Connections	Eight GND pins provide low-inductance return paths - critical for minimizing ground bounce in high-current switching.

Key Features

Feature	Design Value
I_off partial-power-down support	Enables safe operation in mixed-voltage or hot-swap systems by blocking reverse current when V_CC = 0 V.
Edge-rate controlled outputs	Reduces EMI and ground bounce versus standard FCT devices - improves signal integrity on shared bus lines.
Typical output skew < 250 ps	Ensures tight timing alignment across all 16 outputs - essential for synchronous parallel data capture.
64 mA sink / 32 mA source drive	Drives high-capacitance backplanes or long traces without external termination or buffering.
Industrial temperature range	Validated operation from –40°C to +85°C - suitable for factory automation, transportation, and outdoor electronics.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY74FCT162245CTPACT	24 mA balanced drive (sink/source), lower ground bounce (<0.6 V), no high-current sink capability.	Better suited for transmission-line driving with controlled impedance; less appropriate for heavy capacitive loads.	Select when minimizing EMI and ground bounce outweighs raw drive strength - e.g., point-to-point routing on controlled-impedance boards.
CY74FCT162H245CTPACT	Includes bus-hold inputs (no external pull-ups needed); same 24 mA drive as CY74FCT162245CTPACT.	Eliminates floating-input risk in unconnected or intermittently driven bus segments - ideal for modular or field-upgradeable systems.	Choose when input stability during hot-plug or partial configuration is required, and 24 mA drive suffices for target load.

Compared with CY74FCT162245CTPACT and CY74FCT162H245CTPACT, the CY74FCT16245CTPACT uniquely delivers 64 mA sink capability for demanding backplane loads, while retaining I_off, low skew, and industrial temperature rating - making it the only option among the three for high-current, high-capacitance 5V bus interfacing.

FAQ

What is the maximum propagation delay specification for CY74FCT16245CTPACT?

The CY74FCT16245CTPACT has a maximum propagation delay (t_PLH/t_PHL) of 4.1 ns for data transfer between A and B ports under industrial temperature and voltage conditions. This value is guaranteed across the full operating range (–40°C to +85°C, V_CC = 4.5 V to 5.5 V) and reflects worst-case timing for design margining in synchronous 16-bit bus systems.

Does CY74FCT16245CTPACT support partial power-down operation?

Yes, CY74FCT16245CTPACT fully supports partial-power-down operation via its I_off circuitry. When V_CC = 0 V, the device limits I_off current to ±1 µA per I/O pin, preventing damaging backflow current from live buses into the unpowered IC - a key requirement for hot-swap and modular system architectures.

What package type and dimensions does CY74FCT16245CTPACT use?

CY74FCT16245CTPACT uses a 48-pin TSSOP (Thin Shrunk Small Outline Package), designated DGG, with 0.5 mm lead pitch, 12.4–12.6 mm body length, 6.0–6.2 mm body width, and 1.2 mm maximum height. Its footprint matches JEDEC MO-153 standards and supports automated pick-and-place assembly.

How does CY74FCT16245CTPACT handle ground bounce during high-current switching?

CY74FCT16245CTPACT specifies typical V_OLP (ground bounce) of <1.0 V at V_CC = 5 V and T_A = 25°C, achieved through edge-rate control and eight dedicated GND pins. This design minimizes simultaneous switching noise, preserving signal integrity on shared ground planes in dense 16-bit bus implementations.

Can CY74FCT16245CTPACT be used as two independent 8-bit transceivers?

Yes, CY74FCT16245CTPACT supports dual-octal operation: Pins 1DIR/1OE control the first 8-bit segment (1A1–1A8 ↔ 1B1–1B8), while 2DIR/2OE independently manage the second segment (2A1–2A8 ↔ 2B1–2B8). This enables flexible partitioning for separate data and address bus domains within a single package.
