CY74FCT162245ATPVC

Overview

The CY74FCT162245ATPVC is a Fast CMOS octal bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features balanced output drivers with ±24mA current capability. The device provides non-inverting logic functionality across eight channels, housed in a 48-pin SSOP package. It supports surface-mount installation and functions reliably within an operating temperature range of -40°C to +85°C.

Feature Summary

• Balanced output drivers providing symmetrical ±24mA high and low current drive capabilities
• Bus-hold circuitry integrated on all inputs to maintain signal states during inactive periods
• Power-off disable feature allowing outputs to remain in a high-impedance state when VCC is off

Applications

• High-speed data transmission between microprocessors and memory modules
• Buffering and bidirectional data flow control in complex digital systems
• Clock distribution networks requiring stable signal integrity

Procurement Notes

Verify the specific suffix 'TPVC' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with RoHS directives if required for your manufacturing process. Cross-reference the manufacturer part number directly with the datasheet to validate pinout assignments and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require symmetric drive strength for both logic high and low states. The integrated bus-hold feature makes it suitable for applications where input lines must retain their last known state without external pull-up or pull-down resistors. Consider the 48-pin SSOP footprint constraints and thermal dissipation requirements relative to the ±24mA output capability.

Part Context

This device belongs to the FCT (Fast CMOS) logic family from Texas Instruments, designed to bridge the performance gap between standard TTL and advanced CMOS technologies. The FCT series emphasizes high switching speeds combined with low power consumption, making it a standard choice for general-purpose digital logic interfacing in industrial and commercial electronics.

Replacement Considerations

Direct replacements include the CY74FCT162245T and PI74FCT162245T. Verify that substitute components match the 48-pin SSOP physical dimensions and maintain identical pin configurations to ensure board-level compatibility without redesign.
