Product details
Overview
CY74FCT162244CTPVC from Texas Instruments is a 16-bit non-inverting three-state buffer/line driver optimized for high-speed bus interface applications. It features balanced 24-mA output drivers, Ioff partial-power-down support, edge-rate control for noise reduction, and operates at 5V ±10% over –40°C to +85°C. It is used in memory and clock driver circuits requiring low ground bounce and transmission-line compatibility.
For engineers reviewing the CY74FCT162244CTPVC datasheet, CY74FCT162244CTPVC pinout, CY74FCT162244CTPVC application, or CY74FCT162244CTPVC equivalent, key selection criteria include its 24-mA balanced drive strength, 4.1-ns max propagation delay, SSOP-48 package, Ioff-enabled power-down protection, and suitability for noise-sensitive backplane and transmission-line driving.
Technical Context
This device implements four independent 4-bit groups of non-inverting buffers with individual active-low three-state enable inputs (1OE–4OE), enabling flexible 4-, 8-, or full 16-bit bus operation. Its output drivers integrate current-limiting resistors to reduce system switching noise and minimize undershoot.
The Ioff circuitry ensures outputs remain high-impedance when VCC = 0 V, preventing damaging current backflow during partial power-down. Edge-rate control limits slew rate to improve noise immunity without external components, and typical output skew is <250 ps across outputs within the same package.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum propagation delay for CY74FCT162244CTPVC?
The maximum propagation delay (tPLH/tPHL) for CY74FCT162244CTPVC is 4.1 ns over the full industrial temperature range (–40°C to +85°C) and VCC = 4.5 V to 5.5 V. This value is specified in the "Switching Characteristics" table of the official datasheet and applies to all 16 channels under standard load conditions. CY74FCT162244CTPVC maintains consistent timing performance across its operating range, making it suitable for systems requiring tight setup/hold margins.
Does CY74FCT162244CTPVC support partial power-down operation?
Yes, CY74FCT162244CTPVC includes Ioff circuitry that disables all outputs when VCC = 0 V, preventing damaging current backflow during partial power-down or hot-swap events. This feature is fully characterized per JEDEC JESD78 and verified across temperature. CY74FCT162244CTPVC remains safe in mixed-rail systems where other devices may be powered down independently.
What package type is used for CY74FCT162244CTPVC?
CY74FCT162244CTPVC uses a 48-pin SSOP (Shrunk Small Outline Package), designated O48, with 300-mil body width and 0.5-mm lead pitch. It complies with JEDEC MO-153 and is RoHS-compliant. The package includes dual VCC and dual GND pins to reduce supply inductance, and its flow-through pinout simplifies PCB layout for high-speed bus routing.
How does CY74FCT162244CTPVC reduce ground bounce compared to standard FCT buffers?
CY74FCT162244CTPVC reduces ground bounce to <0.6 V (typical) at VCC = 5 V and TA = 25°C by integrating current-limiting resistors in its 24-mA balanced output drivers and employing edge-rate control. This contrasts with CY74FCT16244CTPVC, which exhibits ~1.0 V ground bounce under identical conditions. CY74FCT162244CTPVC achieves this without external components, improving signal integrity on dense, multi-layer boards.
Can CY74FCT162244CTPVC be used in transmission-line applications?
Yes, CY74FCT162244CTPVC is explicitly designed for transmission-line driving. Its ±24-mA balanced output drive, integrated current-limiting resistors, and controlled edge rate allow direct connection to 50-Ω traces without external termination. The datasheet states it is "ideal for driving transmission lines," and measured VOLP <0.6 V confirms low noise behavior essential for clean eye diagrams in point-to-point or daisy-chained configurations.
