Texas Instruments 74FCT162245ATPVCT

Overview

74FCT162245ATPVCT from Texas Instruments is a 16-bit bidirectional transceiver IC with balanced 24-mA output drivers, designed for high-speed synchronous bus communication between two data buses. It operates at 5V ±10%, supports industrial temperature range (–40°C to +85°C), features Ioff partial-power-down protection, and is optimized for transmission-line driving with reduced ground bounce (<0.6V typical) and low switching noise.

For engineers reviewing the 74FCT162245ATPVCT datasheet, 74FCT162245ATPVCT pinout, 74FCT162245ATPVCT application, or 74FCT162245ATPVCT equivalent, key selection criteria include its 4.5-ns max propagation delay (A↔B), 24-mA balanced drive strength, SSOP-48 package compatibility, and bus-noise mitigation features critical for backplane and high-density PCB designs.

Technical Context

This device implements dual 8-bit or unified 16-bit bidirectional data transfer controlled by DIR (direction) and OE (output enable, active-low). Its edge-rate control circuitry limits slew rate to suppress EMI and crosstalk, while Ioff circuitry disables outputs during power-down to prevent backflow current when VCC = 0V.

The 74FCT162245ATPVCT uses CMOS-compatible TTL-input thresholds (VIH = 2.0V min, VIL = 0.8V max), delivers matched HIGH/LOW drive (±24 mA), and maintains <250-ps typical output skew across all 16 outputs-enabling precise timing alignment in parallel bus systems.

FAQ

What is the maximum operating frequency supported by the 74FCT162245ATPVCT?

The 74FCT162245ATPVCT does not specify a maximum clock frequency directly, but its 4.5-ns maximum propagation delay (A↔B) and <250-ps output skew allow reliable operation in synchronous bus systems with clock periods ≥9 ns-supporting effective data rates up to ~110 MHz in well-terminated, low-capacitance layouts. Actual usable frequency depends on trace length, load capacitance, and termination scheme.

Does the 74FCT162245ATPVCT support hot-swap or live-insertion applications?

Yes, the 74FCT162245ATPVCT supports hot-swap applications via its Ioff circuitry, which disables outputs when VCC = 0V to prevent damaging current backflow. This feature, combined with >2000-V HBM ESD rating and robust SSOP-48 mechanical design, makes the 74FCT162245ATPVCT suitable for modular chassis systems where cards are inserted or removed under power.

Can the 74FCT162245ATPVCT be used in 3.3-V systems?

No, the 74FCT162245ATPVCT is strictly a 5-V device with VCC = 5V ±10% operation and TTL-compatible input thresholds (VIH = 2.0V min, VIL = 0.8V max). It is not 3.3-V tolerant-applying 3.3-V signals may result in marginal or non-functional behavior, and powering from 3.3 V will cause failure. For 3.3-V systems, consider SN74LVC16245A or similar LVC-family parts.

How does the 74FCT162245ATPVCT differ from the CY74FCT16245T variant?

The 74FCT162245ATPVCT features balanced ±24-mA output drivers and reduced ground bounce (<0.6 V), whereas the CY74FCT16245T provides asymmetric drive (64 mA sink / 32 mA source) optimized for heavy capacitive loads. The 74FCT162245ATPVCT also includes edge-rate control for lower EMI and is specified for transmission-line driving, unlike the CY74FCT16245T's backplane focus.

Is the 74FCT162245ATPVCT pin-compatible with other members of the FCT162xx45 family?

Yes, the 74FCT162245ATPVCT shares identical pinout and package (SSOP-48) with all CY74FCT162x245T variants-including CT and T speed grades-as confirmed in TI's ordering information tables. Functionally, it differs in drive strength and timing, but mechanical and electrical interface compatibility is maintained across the family for drop-in replacement within the same speed grade and package type.
