74LVT2240WMX

Overview

The onsemi 74LVT2240WMX is an octal buffer and line driver belonging to the LVT logic series. It features eight non-inverting inputs driving corresponding outputs in a unidirectional configuration. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical parameters include a high-level output current of -12 mA and a low-level output current of 12 mA. Static current is specified at 190 uA, with a maximum operating supply current of 5 mA. Propagation delay is 5.3 ns at 2.7 V and 4.4 ns at 3.3 V. It supports surface mount installation in a TSSOP-20 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Octal buffer and line driver architecture providing eight independent signal paths
• Non-inverting polarity for direct signal transmission without phase reversal
• Three-state output capability allowing bus isolation and multi-driver configurations

Applications

• Memory buffer applications in embedded systems

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements for the TSSOP-20 package. Validate pinout compatibility with existing PCB footprints to prevent assembly errors during production.

Selection Notes

Select this component when designing systems requiring octal buffering with 3.3 V logic levels. Consider the LVT series characteristics for low power consumption relative to standard LVCMOS. Evaluate the TSSOP-20 package constraints against available board space. Verify that the 2.7 V minimum supply voltage aligns with the system's power rail stability under all operating conditions.
