74LV244PW,112

Overview

The Nexperia 74LV244PW,112 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.0 V to 5.5 V and utilizes CMOS technology for low power dissipation. The device contains two independent four-bit buffers controlled by separate output enable inputs (1OE and 2OE). It is housed in a TSSOP20 plastic thin shrink small outline package with a body width of 4.4 mm. The component supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Provides eight non-inverting buffered outputs with high-impedance OFF-states controlled by dedicated enable signals.
• Accepts TTL input levels when the supply voltage is between 2.7 V and 3.6 V.
• Includes input clamp diodes allowing interface to voltages exceeding VCC using current limiting resistors.
• Complies with JEDEC standards for various supply voltage ranges and offers ESD protection.

Applications

• Memory module address and data bus buffering
• Clock distribution and buffering
• General-purpose digital signal isolation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature rating. Confirm that the requested part number matches the required logic family specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring wide voltage compatibility and low static power consumption. Ensure the design accommodates the specified propagation delays and output drive capabilities across the intended operating temperature range.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. The LV series is designed for operation down to 1.0 V while maintaining compatibility with standard logic interfaces. The PW suffix indicates the TSSOP20 package variant.

Replacement Considerations

Check for direct cross-references such as the 74LV244D or other manufacturers' equivalents like SN74LVC244. Verify pinout compatibility and electrical characteristics match before substituting.

FAQ

How are the outputs disabled?

A HIGH level on either the 1OE or 2OE input causes the corresponding four outputs to assume a high-impedance OFF-state.

Can the inputs handle voltages higher than VCC?

Yes, the inputs include clamp diodes which allow interfacing to voltages in excess of VCC when used with current-limiting resistors.
