Product details
Overview
CY74FCT162240CTPVC from Texas Instruments is a 16-bit non-inverting three-state buffer/line driver with balanced 24-mA output drivers, designed for high-speed transmission-line driving in industrial bus interfaces. It operates at 5V ±10%, supports partial-power-down via Ioff, delivers <0.6V ground bounce at 25°C, and achieves 4.3 ns max propagation delay in SSOP-48 packaging.
For engineers reviewing the CY74FCT162240CTPVC datasheet, CY74FCT162240CTPVC pinout, CY74FCT162240CTPVC application, or CY74FCT162240CTPVC equivalent, key selection criteria include its 24-mA balanced drive strength, flow-through pinout for PCB layout simplification, Ioff-enabled power-down protection, and compatibility with 5-V TTL/CMOS systems requiring low-noise signal integrity.
Technical Context
This device implements dual 8-bit sections (1A–1Y and 2A–2Y per section, four sections total), each with independent active-low three-state enable (OE) control, enabling flexible 4-, 8-, or 16-bit bus configurations. Its edge-rate control circuitry suppresses switching noise without external termination resistors.
The CY74FCT162240CTPVC uses current-limiting resistors integrated into each output stage to achieve symmetrical 24-mA sink/source capability, minimizing undershoot and reducing system-level ground bounce - critical for clean signal integrity on unterminated transmission lines.

FAQ
What is the maximum operating frequency supported by CY74FCT162240CTPVC?
The CY74FCT162240CTPVC has a maximum propagation delay of 4.3 ns, supporting reliable operation up to approximately 200 MHz in well-terminated transmission-line configurations. Actual usable frequency depends on trace length, load capacitance, and signal integrity design - the device's edge-rate control and low ground bounce help maintain timing margins at these speeds.
Does CY74FCT162240CTPVC support hot-swap or live-insertion scenarios?
Yes, CY74FCT162240CTPVC supports partial-power-down via its Ioff feature: when VCC = 0 V, the outputs enter high-impedance mode and leakage remains ≤±1 µA, preventing damaging current flow from live backplanes into unpowered circuitry - a key requirement for hot-plug capable industrial backplanes.
How does CY74FCT162240CTPVC differ from CY74FCT16240T in output behavior?
CY74FCT162240CTPVC features integrated current-limiting resistors yielding balanced ±24-mA drive and <0.6 V ground bounce, optimized for transmission-line driving. In contrast, CY74FCT16240T provides asymmetric 64-mA sink / 32-mA source drive with higher ground bounce (≤1.0 V), better suited for driving high-capacitance loads like unbuffered memory arrays.
Is CY74FCT162240CTPVC pin-compatible with older 74FCT240-based designs?
CY74FCT162240CTPVC is not pin-compatible with standard 24-pin 74FCT240 devices due to its 48-pin SSOP footprint and 16-bit dual-section architecture. However, it is functionally and pinout-compatible with other 48-pin FCT162240 variants (e.g., SN74FCT162240CTPVC) and serves as a direct upgrade path from CY74FCT16240T in same-package designs.
What package options are available for CY74FCT162240CTPVC?
CY74FCT162240CTPVC is offered exclusively in the 48-pin SSOP (O48) package - 300-mil body width, 25-mil lead pitch, JEDEC MO-153 compliant. While the related CY74FCT162240CTPACT uses TSSOP (DGG), CY74FCT162240CTPVC is specifically the SSOP variant, verified by TI's packaging addendum and orderable part number mapping.
