74FCT162240ETPV

Overview

The IDT74FCT162240ETPV is a high-speed, low-power CMOS bus driver belonging to the FCT logic series. It features four independent functions, each handling four bits of data, resulting in a total configuration of 16-bit width. The device provides inverted outputs and utilizes a 48-pin Thin Shrink Small Outline Package (TSSOP) with a 0.40 mm pitch. It operates within an extended commercial temperature range from -40°C to +85°C and supports power supply voltages between 4.5 V and 5.5 V.

Feature Summary

• Provides four independent 4-bit bidirectional data paths for flexible system interfacing
• Features inverted output polarity suitable for specific logic gate requirements
• Utilizes 0.5-micron CMOS technology for high-speed operation with low power consumption
• Includes three-state outputs with series resistors to manage signal integrity

Applications

• High-speed data bus drivers in computer systems
• Memory buffer applications requiring inverted logic levels
• I/O port expansion in embedded controllers
• Clock distribution networks where phase inversion is required

Procurement Notes

Verify the package marking code matches ETPV for TSSOP-48. Confirm lead finish specifications if RoHS compliance is mandatory, as older batches may differ. Check date codes against current manufacturing status to ensure availability of fresh stock. Validate pin 1 identification on the physical component to prevent orientation errors during assembly.

Selection Notes

Select this component when inverted logic output is explicitly required by the destination circuit. Compare drive strength and propagation delay against non-inverting variants like the 162244 if polarity constraints change. Ensure the 48-pin TSSOP footprint aligns with the PCB layout. Verify that the 4.5V to 5.5V operating range matches the system voltage rails.

Part Context

This part belongs to the IDT 74FCT family of fast CMOS logic devices. It serves as a direct replacement for older ABT series components while offering improved speed and lower power dissipation. The FCT series is widely used in digital systems requiring reliable bus driving capabilities with standard TTL-compatible input thresholds.

Replacement Considerations

Check for cross-reference equivalents from other manufacturers such as ON Semiconductor or Cypress. Verify pin-to-pin compatibility before substitution. Ensure the replacement device maintains the same inverted output characteristic and package dimensions.
