74LV245PW,118

Overview

The Nexperia 74LV245PW,118 is an octal bus transceiver with three-state outputs housed in a TSSOP20 package (SOT360-1). It operates on a supply voltage range of 1.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features low power CMOS dissipation and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. It accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V.

Feature Summary

• Provides eight-bit bidirectional data transfer capability with three-state outputs controlled by OE and DIR pins.
• Includes input clamp diodes allowing interface to voltages exceeding VCC when used with current limiting resistors.
• Offers robust electrostatic discharge protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model.

Applications

• Low voltage memory mapping
• Clock drivers
• Bus-oriented communications

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the TSSOP20 plastic thin shrink small outline package variant. Confirm that the required temperature range matches the specified -40 °C to +125 °C operational limits. Ensure application designs account for the absolute maximum ratings regarding supply voltage and output currents to prevent permanent damage.

Selection Notes

Select this component for applications requiring wide supply voltage flexibility down to 1.0 V. It is suitable for systems needing high ESD protection and compatibility with both CMOS and TTL logic levels within the 2.7 V to 3.6 V range. Consider the TSSOP20 package dimensions for PCB layout constraints.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. It functions as an octal bus transceiver, distinct from standard HC or HCT families by its extended voltage range and specific latch-up performance characteristics defined by JEDEC standards.

Replacement Considerations

Direct pin-compatible replacements may include other manufacturers' 74LV245 variants in TSSOP20 packages. Verify functional equivalence regarding propagation delay and output drive capabilities before substitution.
