74HCT241DB,112

Overview

The 74HCT241DB,112 is an octal buffer and line driver featuring three-state outputs, manufactured by Nexperia. It belongs to the HCT logic series, designed for high-speed CMOS applications with TTL-compatible input levels. The device integrates two independent output enable controls, allowing configuration as a single eight-bit buffer or two four-bit buffers. It operates within a supply voltage range of 2.0 V to 6.0 V and includes input clamp diodes for interfacing with voltages exceeding VCC. The component is housed in a 20-pin SSOP package (SOT339-1) and complies with JEDEC standards JESD8C and JESD7A.

Feature Summary

• Octal bus interface with non-inverting three-state outputs
• TTL-compatible input levels for direct interfacing with standard logic families
• Dual output enable functionality controlling separate four-bit groups
• High noise immunity and robust latch-up performance

Applications

• Memory address and data bus drivers
• Clock distribution circuits
• Control signal buffering in embedded systems

Procurement Notes

Verify the specific suffix '112' against current manufacturer catalogs, as this variant may be obsolete. Confirm package integrity and pin compatibility during replacement sourcing. Ensure the selected substitute maintains HCT input threshold specifications to guarantee logical compatibility with existing TTL-driven interfaces in the design.

Selection Notes

Select this component when designing systems requiring eight-channel signal buffering with isolated control capabilities. The HCT series ensures compatibility with 5V and 3.3V logic families. Consider the SSOP package constraints for PCB layout. Verify that the application environment remains within the specified operating temperature range to maintain signal integrity and timing parameters.

Part Context

This part is a member of the 74HCT241 family, which includes variants like 74HCT241DB,118. The family provides octal buffering solutions for digital systems. While the core function remains consistent across the series, packaging and suffix variations exist. Designers should reference the specific datasheet for the exact electrical characteristics and mechanical dimensions associated with the DB,112 designation.

Replacement Considerations

Check for 74HCT241DB,118 as a potential alternative from the same manufacturer. Verify functional equivalence regarding pinout and electrical specifications before substitution.
