74LV244DB,118

Overview

The Nexperia 74LV244DB,118 is an octal buffer and line driver featuring three-state outputs housed in a SO20 plastic small outline package (SOT163-1). It operates on a supply voltage range of 1.0 V to 5.5 V with low power CMOS dissipation. The device includes two output enables controlling four outputs each, and inputs equipped with clamp diodes for interfacing voltages exceeding VCC. It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36, and supports operating temperatures from -40 °C to +125 °C.

Feature Summary

• Features two independent output enable lines to control separate groups of three-state outputs.
• Includes input clamp diodes allowing interface to voltages higher than the supply voltage using current limiting resistors.
• Provides high latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Applications

• Bus-oriented communications
• Clock drivers
• Buffering memory data

Procurement Notes

Verify the specific ordering suffix '118' against the manufacturer's latest documentation to confirm the exact packaging configuration and reel specifications. Confirm that the SO20 package variant matches the required PCB footprint dimensions. Ensure the component status aligns with long-term availability requirements as product lifecycles may change.

Selection Notes

Select this component when an octal buffer with three-state capability is required for bus applications. Verify that the 1.0 V to 5.5 V supply range meets system voltage needs. Check if the SO20 package fits the design constraints compared to TSSOP alternatives. Ensure input levels are compatible with the TTL input level acceptance between 2.7 V and 3.6 V.

Part Context

This part belongs to the 74LV series of logic devices, designed for low-voltage applications ranging from 1.0 V to 3.6 V while maintaining compatibility with standard logic families. The 74LV244 specifically provides eight buffered outputs, making it suitable for driving multiple loads or extending signal paths in digital circuits requiring isolation or impedance matching.

Replacement Considerations

The 74LV244PW,118 serves as a pin-compatible alternative utilizing a TSSOP20 package instead of the SO20 format. Both variants share identical electrical characteristics and functionality within the same logic family.
