Product details
Overview
74FCT162827ATPVCT from Texas Instruments is a 20-bit non-inverting three-state buffer/line driver with balanced 24 mA output drivers, Ioff partial-power-down support, and 5.0 V ±10% supply operation. It features typical ground bounce <0.6 V, output skew <0.5 ns, and propagation delay of 8.0 ns (CL=50 pF), designed for high-speed transmission-line driving in industrial bus interfaces.
For engineers reviewing the 74FCT162827ATPVCT datasheet, 74FCT162827ATPVCT pinout, 74FCT162827ATPVCT application, or 74FCT162827ATPVCT equivalent, key selection criteria include output drive balance, low ground bounce, Ioff-enabled power-down safety, and SSOP-56 packaging compatibility with 300-mil width and 25-mil pitch.
Technical Context
This device implements dual 10-bit buffered paths, each controlled by a pair of NANDed output-enable inputs (OE1/OE2), enabling flexible channel gating. Its balanced 24 mA sink/source drivers incorporate internal current-limiting resistors to suppress undershoot and reduce reliance on external termination.
The Ioff circuitry actively disables outputs when VCC = 0 V, preventing backflow current during partial power-down-critical for hot-swap and mixed-voltage system interoperability. All logic thresholds comply with TTL input levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and operate across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5.0 V ±10% - ensures compatibility with standard 5-V TTL/CMOS systems without level-shifting. |
| Output Drive | ±24 mA - balanced sink/source capability minimizes ground bounce and supports unterminated transmission lines. |
| Propagation Delay | 8.0 ns max (CL = 50 pF) - enables reliable 125 MHz bus operation with timing margin. |
| Ground Bounce (VOLP) | <0.6 V at VCC = 5 V, TA = 25°C - reduces noise coupling into adjacent signals and power rails. |
| Ioff Support | Active at VCC = 0 V - prevents damaging current flow during partial power-down or hot insertion. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded control and communications equipment. |
| Input Hysteresis | 100 mV - improves noise immunity on slow-rising or noisy enable/control lines. |
Pinout & Package
74FCT162827ATPVCT is housed in a 56-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 25-mil lead pitch, compliant with JEDEC MO-153 and RoHS Green (Pb-free, no Sb/Br) standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A1–1A10, 2A1–2A10 | Data Inputs | Two independent 10-bit input buses accepting TTL-level signals. |
| 1Y1–1Y10, 2Y1–2Y10 | Three-State Outputs | 20 buffered, non-inverting outputs with 24 mA drive strength and Ioff protection. |
| 1OE1, 1OE2, 2OE1, 2OE2 | Output Enable (Active LOW) | NAND-gated pairs per 10-bit section allow granular output control and reduced enable logic overhead. |
| VCC (Pins 25, 36, 47) | Power Supply | Multiple VCC pins minimize IR drop and improve high-frequency decoupling across wide die. |
| GND (Pins 26, 37, 48, 56) | Ground Reference | Distributed GND pins reduce ground loop inductance and stabilize output switching behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Balanced ±24 mA outputs | Eliminates need for external series termination on PCB traces up to 15 cm, reducing BOM count and layout complexity. |
| Ioff partial-power-down | Enables safe insertion/removal in live backplanes without risk of latch-up or bus contention from unpowered devices. |
| Typical output skew <0.5 ns | Ensures deterministic timing alignment across all 20 outputs-critical for parallel data capture and synchronous bus designs. |
| Low ground bounce (<0.6 V) | Maintains signal integrity in dense, multi-driver environments where simultaneous switching noise could corrupt adjacent channels. |
| TTL-compatible inputs | Direct interface with legacy 5-V microcontrollers, FPGAs, and ASICs without level translators or pull-up networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 20-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT162827ATPVC | Same silicon, identical electrical specs, but packaged in 56-pin SSOP with 300-mil width and 25-mil pitch - pinout and footprint identical to 74FCT162827ATPVCT. | No functional difference; both rated for industrial temperature range and share identical timing, drive, and Ioff behavior. | Select CY74FCT162827ATPVC if sourcing from Cypress-branded TI inventory or requiring legacy part marking (FCT162827A). |
| 74FCT162827CTPVCT | Faster 4.2 ns propagation delay (vs. 8.0 ns), same package, same Ioff and drive strength - higher speed grade within same family. | Suitable where tighter timing budgets exist (e.g., >200 MHz bus clocking), but requires validation of downstream setup/hold margins. | Choose 74FCT162827CTPVCT only when the design requires sub-5 ns propagation; otherwise, 74FCT162827ATPVCT offers optimal cost/performance balance for 100–125 MHz applications. |
Compared with CY74FCT162827ATPVC, 74FCT162827ATPVCT shares identical pinout and performance but reflects TI's standardized ordering nomenclature; versus 74FCT162827CTPVCT, it trades 3.8 ns of delay for lower dynamic power and relaxed timing margin requirements-making it preferable for thermally constrained or cost-sensitive industrial systems.

FAQ
What is the maximum operating frequency supported by the 74FCT162827ATPVCT?
The 74FCT162827ATPVCT has a maximum propagation delay of 8.0 ns under CL = 50 pF conditions, supporting reliable operation up to approximately 125 MHz for single-cycle bus transactions. Actual usable frequency depends on board layout, load capacitance, and timing margins required by downstream receivers-designers should verify setup/hold times using worst-case delay values from the datasheet.
Does the 74FCT162827ATPVCT support hot-swap or partial-power-down operation?
Yes, the 74FCT162827ATPVCT integrates Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during hot-insertion or partial power-down scenarios. This feature is fully characterized per JEDEC JESD78 and enables safe use in modular backplane systems where boards may be inserted or removed while the main chassis remains powered.
What package type and dimensions does the 74FCT162827ATPVCT use?
The 74FCT162827ATPVCT uses a 56-pin SSOP (Shrink Small Outline Package) with 300-mil body width, 25-mil lead pitch, and 1.2 mm max height. Its JEDEC MO-153-compliant footprint measures 13.9 mm × 7.9 mm, with pin 1 marked by a notch and located in the top-left corner when viewed from the top with the notch facing upward.
How does the 74FCT162827ATPVCT differ from the CY74FCT16827T series?
The 74FCT162827ATPVCT features balanced ±24 mA outputs with integrated current-limiting resistors and lower ground bounce (<0.6 V), whereas the CY74FCT16827T delivers asymmetric drive (64 mA sink / 32 mA source) optimized for high-capacitance loads. Their pinouts are identical, but output characteristics and noise performance are tailored to different routing topologies-transmission lines vs. backplanes.
Is the 74FCT162827ATPVCT RoHS compliant and lead-free?
Yes, the 74FCT162827ATPVCT is RoHS compliant and manufactured under TI's "Green" eco-plan: Pb-free with no bromine or antimony-based flame retardants.
