Product details
Overview
74FCT162240CTPVCT from Texas Instruments is a 16-bit non-inverting three-state buffer/line driver with balanced 24-mA output drive, designed for high-speed transmission-line driving in industrial bus interfaces. It operates at 5V ±10%, supports partial-power-down via IOFF, delivers typical output skew <250 ps, and features edge-rate control to reduce ground bounce (<0.6 V) in backplane and memory driver applications.
For engineers reviewing the 74FCT162240CTPVCT datasheet, 74FCT162240CTPVCT pinout, 74FCT162240CTPVCT application, or 74FCT162240CTPVCT equivalent, key selection criteria include its 4.3-ns max propagation delay, flow-through pinout for simplified PCB routing, TSSOP/SSOP package compatibility, and IOFF-enabled system-level power sequencing in mixed-voltage environments.
Technical Context
This device implements dual 8-bit sections (1A–1Y and 2A–2Y per side), each with independent active-low three-state enable (1OE, 2OE), enabling flexible 4-, 8-, or 16-bit bus configurations. Its balanced 24-mA sink/source drivers incorporate internal current-limiting resistors to suppress undershoot and minimize termination requirements on controlled-impedance traces.
The IOFF circuitry actively disables outputs when VCC = 0 V, blocking reverse current flow up to ±4.5 V at output pins - critical for hot-swap and partial-power-down systems. Edge-rate control ensures clean signal transitions without excessive EMI, while input hysteresis (100 mV) improves noise immunity on noisy bus lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5 V ±10% - compatible with standard TTL/CMOS logic rails; no level-shifting required in 5-V systems. |
| Propagation Delay | Max 4.3 ns (tPLH/tPHL) - enables reliable operation in >200-MHz bus clock domains with timing margin. |
| Output Drive | ±24 mA balanced - eliminates need for external series termination on 50-Ω transmission lines. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V - reduces simultaneous switching noise in dense multi-driver layouts. |
| IOFF Protection | ±1 µA at VCC = 0 V - prevents backflow damage during power sequencing or hot insertion. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control, instrumentation, and telecom infrastructure. |
| Input Hysteresis | 100 mV - rejects noise on slow-rising or unterminated bus signals without external Schmitt triggers. |
Pinout & Package
74FCT162240CTPVCT is packaged in a 48-lead SSOP (O48), 300-mil body width, 0.025-inch pitch, 1.2-mm max height. Pin 1 marked with notch or dot; pinout follows flow-through architecture to minimize trace crossovers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A8, 2A1–2A8 | Data Inputs (two 8-bit groups) | Non-inverting inputs accepting TTL/CMOS logic levels; VIH ≥2.0 V, VIL ≤0.8 V. |
| 1Y1–1Y8, 2Y1–2Y8 | Three-State Outputs (two 8-bit groups) | Active-high buffered outputs; high-impedance when corresponding OE is HIGH. |
| 1OE, 2OE | Active-Low Output Enables | Independent controls per 8-bit section; enables mixed-width bus operation (e.g., 8-bit + 8-bit or 16-bit). |
| VCC (Pins 24, 48) | Power Supply | Dual VCC pins reduce supply inductance and improve transient response across wide bus. |
| GND (Pins 25, 47) | Ground Reference | Dual GND pins provide low-inductance return path; critical for maintaining low VOLP under fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24-mA output drivers | Enables direct drive of 50-Ω transmission lines without external resistors, reducing BOM count and layout area. |
| IOFF partial-power-down support | Prevents damaging current backflow when VCC is off, allowing safe integration into multi-rail power systems. |
| Edge-rate controlled outputs | Reduces EMI and crosstalk in high-density routing; eliminates need for external slew-rate limiting components. |
| Flow-through pinout | Input-to-output alignment minimizes layer changes and vias, lowering signal integrity risk in high-speed PCBs. |
| Industrial temperature range | Validated operation from –40°C to +85°C ensures reliability in factory automation, motor drives, and base station equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit three-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16240T | Higher 64-mA sink / 32-mA source drive; no internal current-limiting resistors. | Better suited for driving heavy capacitive loads (>100 pF) or low-impedance backplanes requiring stronger drive. | Select CY74FCT16240T when ground bounce is less critical than raw drive strength; requires external termination. |
| SN74LVC16244ADGGR | 3.3-V only operation; lower 24-mA drive; CMOS input thresholds; no IOFF. | Designed for modern low-voltage systems; incompatible with 5-V buses or partial-power-down architectures. | Choose SN74LVC16244ADGGR only in 3.3-V-only designs where legacy 5-V interoperability is not required. |
Compared with CY74FCT16240T and SN74LVC16244ADGGR, the 74FCT162240CTPVCT uniquely balances 5-V compatibility, IOFF safety, and transmission-line optimization - making it the preferred choice for industrial 5-V bus expansion where signal integrity and power sequencing coexist.

FAQ
What is the maximum operating frequency supported by the 74FCT162240CTPVCT?
The 74FCT162240CTPVCT does not specify a maximum clock frequency directly, but its 4.3-ns propagation delay enables reliable use in bus systems operating up to 200 MHz with appropriate setup/hold margins. System-level timing depends on load capacitance, trace length, and driver-receiver pairing - actual frequency must be validated per layout and signal integrity analysis.
Does the 74FCT162240CTPVCT support hot-swap or live-insertion?
Yes, the 74FCT162240CTPVCT supports hot-swap via its IOFF circuitry, which disables outputs and limits reverse current to ±1 µA when VCC = 0 V. This protects the device and upstream circuitry during live insertion into powered backplanes - provided output voltages remain within –0.5 V to +4.5 V during insertion.
Can the 74FCT162240CTPVCT drive 50-Ω transmission lines without external series resistors?
Yes, the 74FCT162240CTPVCT's ±24-mA balanced output drivers are designed to match 50-Ω lines directly. Internal current-limiting resistors suppress reflections and undershoot, eliminating the need for discrete 33-Ω or 49.9-Ω series terminators typically used with higher-drive buffers like the CY74FCT16240T.
What is the purpose of the two separate output-enable pins (1OE and 2OE) on the 74FCT162240CTPVCT?
The dual active-low enables (1OE and 2OE) allow independent control of the two 8-bit output groups (1Y1–1Y8 and 2Y1–2Y8). This enables flexible bus segmentation - for example, using one group for address lines and the other for data, or time-multiplexing 8-bit sub-buses without full 16-bit contention.
Is the 74FCT162240CTPVCT pin-compatible with the CY74FCT16240T?
Yes, the 74FCT162240CTPVCT shares identical pinout, package (SSOP O48), and functional block diagram with the CY74FCT16240T. However, output drive strength, ground bounce, and internal termination differ - so while PCB layout is reusable, signal integrity validation is required when substituting between them.
