Texas Instruments CY74FCT162245CTPVC

Overview

CY74FCT162245CTPVC 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 delivers typical output skew <250 ps - ideal for driving transmission lines and low-impedance backplanes.

For engineers reviewing the CY74FCT162245CTPVC datasheet, CY74FCT162245CTPVC pinout, CY74FCT162245CTPVC application, or CY74FCT162245CTPVC equivalent, key selection criteria include its 24-mA balanced drive strength, 4.1-ns max propagation delay, ground-bounce performance (<0.6 V), SSOP-48 package compatibility, and bus-noise-reduction architecture.

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 reduce system switching noise and EMI, while integrated current-limiting resistors minimize undershoot and eliminate need for external termination on transmission lines.

The CY74FCT162245CTPVC uses FCT logic family characteristics: TTL-compatible inputs, CMOS-level outputs, and Ioff protection enabling live insertion and partial power-down operation without damaging current backflow. It does not include bus-hold circuitry - unlike the CY74FCT162H245T variant - and requires externally biased inputs when floating.

FAQ

What is the maximum propagation delay specification for CY74FCT162245CTPVC?

The CY74FCT162245CTPVC has a maximum propagation delay of 4.1 ns (tPLH/tPHL) for data transfer between ports A and B over the full industrial temperature range (–40°C to +85°C) at VCC = 4.5 V to 5.5 V. This value is measured under standard load conditions and ensures timing compliance in systems operating up to 200-MHz effective bus rates.

Does CY74FCT162245CTPVC include bus-hold circuitry on its inputs?

No, CY74FCT162245CTPVC does not include bus-hold functionality. Unlike the CY74FCT162H245CTPVC variant, this part requires externally applied pull-up or pull-down resistors on unused or undriven inputs to prevent floating states and potential logic instability. The absence of bus-hold is explicitly confirmed in the functional description and pin feature tables.

What package type and dimensions does CY74FCT162245CTPVC use?

CY74FCT162245CTPVC uses a 48-pin SSOP (Shrink Small Outline Package) with 300-mil body width and 0.025-inch lead pitch (O48), conforming to JEDEC MO-153. Its mechanical outline specifies 12.4–12.6 mm length, 6.0–6.2 mm width, and ≤1.2 mm height - optimized for high-density PCB layouts while maintaining hand-solderability and reflow compatibility.

Can CY74FCT162245CTPVC operate with partial power-down enabled?

Yes, CY74FCT162245CTPVC supports partial-power-down mode via its Ioff circuitry. When VCC = 0 V, the outputs enter high-impedance state and leakage current is limited to ±1 µA, preventing damaging current backflow from live buses into the unpowered device - a key requirement for hot-plug and modular system architectures.

What is the output drive capability of CY74FCT162245CTPVC at VCC = 5 V?

At VCC = 5 V, CY74FCT162245CTPVC provides balanced ±24 mA output drive (IODH/IODL), meaning it sources and sinks equal current. This symmetry ensures consistent rise/fall times and reduced ground bounce (<0.6 V typical), directly supporting clean signal transitions on transmission lines without external termination components.
