Product details
Overview
CY74FCT162245TPVC from Texas Instruments is a 16-bit non-inverting bus transceiver with balanced 24-mA output drivers, designed for bidirectional synchronous communication between two buses in high-speed digital systems. It operates at 5V ±10%, supports industrial temperature range (–40°C to +85°C), features Ioff partial-power-down protection, and is optimized for driving transmission lines with low ground bounce (<0.6V).
For engineers reviewing the CY74FCT162245TPVC datasheet, CY74FCT162245TPVC pinout, CY74FCT162245TPVC application, or CY74FCT162245TPVC equivalent, key selection criteria include its 4.5-ns max propagation delay, 24-mA balanced drive strength, SSOP-48 package compatibility, and bus-noise-reduction architecture for signal integrity-critical backplane and memory interface designs.
Technical Context
This device implements dual 8-bit or unified 16-bit bidirectional data flow controlled by DIR and active-low OE signals. Its balanced output drivers incorporate internal current-limiting resistors to minimize undershoot and reduce system switching noise without external termination.
The CY74FCT162245TPVC integrates Ioff circuitry to disable outputs during power-down, preventing damaging backflow current, and features edge-rate control that ensures typical output skew <250 ps and ESD tolerance >2000V per MIL-STD-883.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY74FCT16245TPVC | Higher drive (64 mA sink / 32 mA source), no current-limiting resistors - requires external termination. | Better suited for driving high-capacitance loads and low-impedance backplanes, not optimized for transmission-line signaling. | Select when interfacing to unterminated heavy loads; avoid where low ground bounce is critical. |
| CY74FCT162H245TPVC | Includes bus-hold inputs (no external pull-ups needed), identical 24-mA drive and timing specs. | Preferred in systems with floating or high-impedance control buses where input state retention is required during sleep modes. | Choose when eliminating external bias resistors on DIR/OE or data lines is a layout or BOM priority. |
Compared with CY74FCT162245TPVC, CY74FCT16245TPVC delivers higher current but increases ground bounce risk, while CY74FCT162H245TPVC adds bus-hold functionality without compromising drive or timing-making it ideal for power-aware systems needing input state retention.

FAQ
What is the maximum propagation delay specification for CY74FCT162245TPVC?
The CY74FCT162245TPVC has a maximum propagation delay of 4.5 ns (A↔B or B↔A) over the full industrial temperature range (–40°C to +85°C) at VCC = 4.5V. This value is measured under standard load conditions and ensures deterministic timing for 16-bit parallel data paths operating up to 220 MHz.
Does CY74FCT162245TPVC support partial power-down operation?
Yes, CY74FCT162245TPVC includes Ioff circuitry that disables all outputs when VCC = 0V, preventing damaging current backflow during hot-swap or partial-power-down scenarios. This feature is fully specified and tested per JEDEC standards, making CY74FCT162245TPVC suitable for modular backplane and field-upgradeable systems.
What package type is used for CY74FCT162245TPVC?
CY74FCT162245TPVC uses a 48-pin SSOP (Shrunk Small Outline Package) with 300-mil body width and 0.025-inch lead pitch (package code O48). It is RoHS-compliant, rated for industrial temperature operation, and compatible with standard reflow soldering profiles per JEDEC J-STD-020.
How does CY74FCT162245TPVC reduce ground bounce compared to standard FCT transceivers?
CY74FCT162245TPVC reduces ground bounce to <0.6V (typical at VCC = 5V, TA = 25°C) using balanced ±24-mA output drivers with integrated current-limiting resistors. This design minimizes transient current spikes during switching, eliminating the need for external series termination and improving signal integrity on shared ground planes.
Can CY74FCT162245TPVC be used as two independent 8-bit transceivers?
Yes, CY74FCT162245TPVC supports dual 8-bit operation via separate DIR and OE controls for Ports 1 and 2 (1DIR/1OE and 2DIR/2OE). Each 8-bit section functions independently-enabling flexible bus partitioning, isolated data routing, or mixed-voltage domain bridging within a single SSOP-48 footprint.
