Texas Instruments CY74FCT162244TPVCT

Overview

CY74FCT162244TPVCT 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 transmission-line driving. It operates at VCC = 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 CY74FCT162244TPVCT datasheet, CY74FCT162244TPVCT pinout, CY74FCT162244TPVCT application, or CY74FCT162244TPVCT equivalent, key selection criteria include its 24-mA balanced drive strength, ground-bounce reduction (<0.6V VOLP), flow-through pinout for PCB layout simplification, and SSOP-48 package compatibility with legacy 300-mil footprint designs.

Technical Context

This device implements four independent 4-bit groups of non-inverting buffers, each controlled by dedicated active-low OE inputs (1OE–4OE), enabling flexible 4-bit, 8-bit, or full 16-bit bus operation. Its output drivers integrate current-limiting resistors to minimize undershoot and reduce reliance on external termination.

The Ioff circuitry ensures outputs are disabled and high-impedance when VCC = 0V, preventing backflow current during partial power-down. Edge-rate control circuitry is embedded to suppress switching noise, and bus hold functionality is absent-distinguishing it from the CY74FCT162H244T variant.

FAQ

What is the maximum operating frequency supported by CY74FCT162244TPVCT?

CY74FCT162244TPVCT does not specify a maximum clock frequency directly, but its 6.5-ns maximum propagation delay supports reliable operation up to approximately 150 MHz in point-to-point configurations. Actual usable frequency depends on trace length, load capacitance, and termination scheme; for 50-Ω transmission lines, it maintains signal integrity up to 100 MHz with minimal overshoot.

Does CY74FCT162244TPVCT include bus-hold circuitry on its inputs?

No, CY74FCT162244TPVCT does not include bus-hold functionality. Its inputs require explicit logic-level biasing-either to VCC or GND-when not actively driven. This distinguishes it from the CY74FCT162H244TPVCT variant, which integrates bus-hold on all data inputs to prevent floating states.

What package type and dimensions does CY74FCT162244TPVCT use?

CY74FCT162244TPVCT uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width (12.4–12.6 mm), 0.635-mm lead pitch, and 1.2-mm maximum height. It complies with JEDEC MO-153 and shares footprint compatibility with other O48-packaged FCT-family devices.

Can CY74FCT162244TPVCT be used in hot-swap applications?

Yes, CY74FCT162244TPVCT supports hot-swap operation via its Ioff circuitry, which disables outputs and blocks reverse current flow when VCC = 0V. This protects both the device and upstream circuitry during live insertion or removal in backplane and modular system architectures.

How does the edge-rate control in CY74FCT162244TPVCT improve system noise performance?

The edge-rate control circuitry in CY74FCT162244TPVCT intentionally limits output slew rate, reducing di/dt-induced ground bounce and crosstalk. This results in significantly lower simultaneous switching noise (SSN), especially critical in multi-driver configurations on shared power/ground planes, and helps meet Class B EMC requirements without added filtering.
