Product details
Overview
74FCT162244CTPVCT from Texas Instruments is a 16-bit non-inverting three-state buffer/line driver with balanced 24-mA output drivers, designed for high-speed bus interface applications including memory and clock distribution. It operates at 5V ±10%, supports –40°C to +85°C industrial temperature range, features Ioff partial-power-down protection, and delivers typical output skew <250 ps.
For engineers reviewing the 74FCT162244CTPVCT datasheet, 74FCT162244CTPVCT pinout, 74FCT162244CTPVCT application, or 74FCT162244CTPVCT equivalent, key selection criteria include its 24-mA balanced drive strength, ground bounce <0.6V, propagation delay ≤4.1 ns, and SSOP-48 package compatibility with transmission-line driving requirements.
Technical Context
This device implements four independent 4-bit groups of non-inverting buffers, each with dedicated active-low three-state enable (OE) inputs enabling flexible 4-, 8-, or full 16-bit bus control. Its flow-through pinout minimizes PCB trace length and crosstalk in high-density layouts.
The 74FCT162244CTPVCT integrates current-limiting resistors in both sourcing and sinking paths, delivering symmetrical 24-mA drive capability while reducing system-level switching noise and eliminating need for external termination. Ioff circuitry ensures outputs remain high-impedance during power-down, preventing backflow current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5V ±10% - compatible with standard TTL/CMOS logic rails and eliminates need for voltage translation. |
| Output Drive | ±24 mA - balanced sourcing/sinking enables clean signal integrity on unterminated transmission lines. |
| Propagation Delay | ≤4.1 ns - supports >200 MHz bus operation with tight timing margins in high-speed digital systems. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - reduces noise coupling into adjacent signals and power rails. |
| Ioff Support | Enabled - prevents damaging current backflow when VCC = 0 V, critical for hot-swap and partial-power-down designs. |
| ESD Rating | >2000 V HBM - meets industrial robustness requirements without external protection components. |
| Operating Temp | –40°C to +85°C - qualified for use in industrial control, telecom infrastructure, and embedded computing environments. |
Pinout & Package
74FCT162244CTPVCT is housed in a 48-pin SSOP (Shrink Small Outline Package), 300-mil body width, 0.635-mm pitch, 1.2-mm max height, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data Inputs (Grouped) | Four independent 4-bit input banks accepting TTL/CMOS logic levels; no bus hold function. |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | Three-State Outputs | Corresponding non-inverting buffered outputs; high-impedance when respective OE is HIGH. |
| 1OE, 2OE, 3OE, 4OE | Active-Low Output Enables | Independent control per 4-bit group; LOW enables outputs, HIGH disables to high-Z state. |
| VCC (Pins 24, 48) | Power Supply | Dual VCC pins reduce supply inductance and improve noise immunity across wide bus operation. |
| GND (Pins 1, 25) | Ground Reference | Dual GND pins provide low-inductance return path for all 16 drivers, minimizing ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24-mA output drivers | Enables matched rise/fall times and reduced EMI when driving 50-Ω transmission lines without external termination. |
| Edge-rate control circuitry | Actively limits slew rate to suppress simultaneous switching noise (SSN) and improve signal integrity in dense PCB layouts. |
| Ioff partial-power-down support | Guarantees high-impedance outputs even when VCC = 0 V, allowing safe insertion/removal in live backplane systems. |
| Flow-through pinout | Input-to-output signal routing across opposite sides simplifies layer stacking and minimizes trace stubs in multi-layer boards. |
| Low ground bounce (<0.6 V) | Reduces voltage perturbation on shared ground planes, preserving noise margin for adjacent analog or mixed-signal circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16244CTPVCT | Higher drive: 64 mA sink / 32 mA source; asymmetric output strength; higher ground bounce (~1.0 V). | Better suited for driving heavy capacitive loads (>100 pF) or low-impedance backplanes; less optimal for controlled-impedance transmission lines. | Select when maximum fanout into unterminated loads is required; avoid where signal integrity on 50-Ω lines is critical. |
| 74FCT162H244CTPVCT | Includes bus-hold circuitry on all inputs; retains last logic state during floating conditions; identical 24-mA drive and timing. | Eliminates need for external pull-up/down resistors in systems with intermittent bus activity or hot-plug interfaces. | Choose when input stability during tri-state or disconnected states is essential; adds ~100 µA input leakage per pin. |
Compared with 74FCT162244CTPVCT, CY74FCT16244CTPVCT offers greater drive but compromises transmission-line signal integrity, while 74FCT162H244CTPVCT adds bus-hold functionality at no timing cost-making it ideal for systems requiring input state retention without external biasing.

FAQ
What is the maximum operating frequency supported by the 74FCT162244CTPVCT?
The 74FCT162244CTPVCT supports reliable operation up to approximately 240 MHz, derived from its 4.1 ns maximum propagation delay (tPLH/tPHL) and sub-250 ps output skew. This enables use in high-speed parallel bus systems such as memory interfaces and FPGA I/O expansion where timing margins must be tightly controlled.
Does the 74FCT162244CTPVCT support hot-swap or partial-power-down operation?
Yes, the 74FCT162244CTPVCT includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow through powered-down sections of a system. This makes the 74FCT162244CTPVCT suitable for hot-pluggable modules and partial-power-down architectures in industrial backplanes and modular controllers.
What package type and dimensions does the 74FCT162244CTPVCT use?
The 74FCT162244CTPVCT uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width, 0.635-mm lead pitch, and 1.2-mm maximum height. It complies with JEDEC MO-153 and is footprint-compatible with other SSOP-48 logic devices in the FCT family.
How does the 74FCT162244CTPVCT differ from the CY74FCT16244CTPVCT?
The 74FCT162244CTPVCT provides balanced ±24-mA output drive with lower ground bounce (<0.6 V), optimized for transmission-line driving. In contrast, the CY74FCT16244CTPVCT delivers asymmetric 64-mA sink / 32-mA source drive and higher ground bounce (~1.0 V), making it better for heavy capacitive loads but less suitable for controlled-impedance routing.
Is the 74FCT162244CTPVCT RoHS-compliant and lead-free?
Yes, the 74FCT162244CTPVCT is RoHS-compliant and manufactured with lead-free terminations. TI's packaging documentation confirms "RoHS Exempt" status is not applied-full compliance with Directive 2011/65/EU applies, and the device uses matte tin lead finish suitable for standard Pb-free reflow profiles.
