Product details
Overview
74FCT162245CTPVCG4 from Texas Instruments is a 16-bit bidirectional bus transceiver with balanced 24-mA output drivers, Ioff partial-power-down support, and industrial-grade operation (–40°C to +85°C) at VCC = 5V ±10%. It enables high-speed, low-noise data transfer between synchronous buses in backplane and transmission-line applications.
For engineers reviewing the 74FCT162245CTPVCG4 datasheet, 74FCT162245CTPVCG4 pinout, 74FCT162245CTPVCG4 application, or 74FCT162245CTPVCG4 equivalent, key selection criteria include its 4.1-ns max propagation delay, 0.5-ns output skew, 24-mA balanced drive strength, ground-bounce performance (<0.6V), and SSOP-48 package compatibility with legacy 300-mil footprint designs.
Technical Context
This device operates as a dual-octal or unified 16-bit transceiver controlled by DIR (direction) and OE (output enable, active-low). Its Ioff circuitry disables outputs during power-down to prevent current backflow, while edge-rate control minimizes switching noise and EMI.
It features TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), 4.5-pF typical input capacitance, and supports bidirectional data flow between two 16-bit buses without external termination-enabled by integrated current-limiting resistors in each output driver.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPLH/tPHL) | Max 4.1 ns - ensures sub-5-ns timing margin for 100-MHz bus cycles |
| Output Drive Strength | ±24 mA balanced - eliminates need for external series termination on transmission lines |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V - reduces signal integrity risk in dense PCB layouts |
| Output Skew (tSK(O)) | 0.5 ns - maintains tight timing alignment across all 16 outputs |
| Supply Voltage Range | 5 V ±10% - compatible with standard 5-V logic rails and tolerant of rail droop |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| Ioff Support | Enabled - prevents damaging back-current when VCC = 0 V, critical for hot-swap systems |
Pinout & Package
74FCT162245CTPVCG4 is housed in a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 25-mil lead pitch. The package is RoHS-compliant, surface-mountable, and designed for reflow soldering per JEDEC MO-153.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Inputs | Set data flow direction per octal section: LOW = B→A, HIGH = A→B |
| 1OE, 2OE | Output Enable Inputs (Active LOW) | Enable/disable respective 8-bit transceiver sections; HIGH = high-impedance isolation |
| 1A1–1A8, 2A1–2A8 | Port A Data Terminals | Bi-directional I/O pins for first and second octal bus segments |
| 1B1–1B8, 2B1–2B8 | Port B Data Terminals | Bi-directional I/O pins paired with Port A for full 16-bit bidirectional transfer |
| VCC (Pins 24, 25, 47, 48) | Power Supply | Four dedicated VCC pins reduce supply inductance and improve noise immunity |
| GND (Pins 12, 13, 26, 27, 39, 40) | Ground | Six GND pins provide low-impedance return paths and minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24-mA output drivers | Reduces system-level undershoot/overshoot and eliminates external termination resistors on matched-impedance traces |
| Ioff partial-power-down protection | Prevents reverse current flow when VCC is unpowered, enabling safe insertion/removal in live backplanes |
| Edge-rate controlled outputs | Minimizes simultaneous switching noise (SSN) and radiated emissions in high-density digital systems |
| Low ground bounce (<0.6 V) | Maintains stable reference for adjacent logic, reducing timing jitter and false triggering in mixed-signal boards |
| Industrial temperature range | Validated operation from –40°C to +85°C without performance degradation or derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74FCT162245ATPVC | 4.5-ns max propagation delay vs. 4.1 ns; otherwise identical electrical specs and pinout | Suitable for less timing-critical upgrades where 0.4-ns margin is acceptable | Select when cost sensitivity outweighs marginal timing advantage of 74FCT162245CTPVCG4 |
| SN74FCT162245CPAG | Same speed grade but in 48-pin TSSOP (DGG) package with 240-mil width and 0.5-mm pitch | Requires PCB layout change; better thermal dissipation but incompatible with SSOP-48 footprints | Choose only if new design allows TSSOP-48 and benefits from lower profile (1.2 mm max height) |
Compared with 74FCT162245ATPVC, the 74FCT162245CTPVCG4 delivers tighter timing control for high-frequency bus arbitration; compared with SN74FCT162245CPAG, it retains legacy SSOP-48 compatibility essential for drop-in replacements in fielded equipment.

FAQ
What is the maximum operating frequency supported by the 74FCT162245CTPVCG4?
The 74FCT162245CTPVCG4 does not specify a maximum clock frequency directly, but its 4.1-ns propagation delay and 0.5-ns output skew enable reliable operation in 100-MHz synchronous bus systems. Timing margins must be verified against system-level setup/hold requirements, load capacitance, and trace length-especially when driving >30-pF loads or >15-cm traces.
Does the 74FCT162245CTPVCG4 support hot-swap operation?
Yes, the 74FCT162245CTPVCG4 supports hot-swap operation via its Ioff circuitry, which disables outputs and blocks current backflow when VCC = 0 V. This feature protects upstream and downstream circuitry during live insertion into powered backplanes-a key requirement for modular industrial control systems.
Can the 74FCT162245CTPVCG4 be used as two independent 8-bit transceivers?
Yes, the 74FCT162245CTPVCG4 can operate as two independent octal transceivers using separate DIR and OE controls (1DIR/1OE for bits A1–B8, 2DIR/2OE for bits A9–B16). This configuration allows asynchronous data flow between distinct subsystems while sharing the same 5-V supply and ground network.
What is the purpose of the current-limiting resistors inside the 74FCT162245CTPVCG4 outputs?
The internal current-limiting resistors in the 74FCT162245CTPVCG4 outputs reduce edge slew rate and dampen reflections on transmission lines, minimizing undershoot, overshoot, and ground bounce. They eliminate the need for discrete series termination resistors in point-to-point or short-drop bus topologies, simplifying layout and reducing BOM count.
Is the 74FCT162245CTPVCG4 pin-compatible with older 74FCT16245 variants?
No-the 74FCT162245CTPVCG4 is not pin-compatible with the 74FCT16245T family. While both use 48-pin SSOP packages, their output drive strengths differ (24 mA vs. 32/64 mA), and the 74FCT16245T lacks the balanced driver architecture and ground-bounce optimization of the 74FCT162245CTPVCG4. Direct substitution may cause signal integrity issues or excessive loading.
