TPIC6B259N

Overview

The TPIC6B259N is an 8-bit addressable latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features inverting outputs with a propagation delay of 150 ns at 5 V. The device supports a single input line and eight output lines, consuming 300 uA of operating current. It is housed in a PDIP-20 package designed for through-hole mounting. The component functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Provides 8-bit latching capability with addressable control
• Features inverting output polarity for signal management
• Supports high-temperature operation up to 125 °C

Applications

• Industrial control systems requiring latch functionality
• High-temperature electronic environments
• Through-hole PCB designs needing 8-bit data storage

Procurement Notes

Verify the specific orderable part number against the manufacturer's official documentation to ensure compatibility with required packaging and environmental specifications. Confirm that the PDIP-20 through-hole package aligns with the target printed circuit board layout constraints. Cross-reference the electrical parameters, specifically the 4.5 V to 5.5 V supply range, with the system power design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a robust 8-bit latch is required for through-hole assembly processes. The wide operating temperature range makes it suitable for demanding industrial applications where standard commercial grade parts may fail. Ensure the design accommodates the inverting output characteristic and the specified propagation delay for timing-sensitive logic circuits.

Part Context

This device belongs to the TPIC6B259 series of addressable latches produced by Texas Instruments. It serves as a specialized logic integrated circuit designed for reliable data retention in digital systems. The PDIP-20 variant specifically targets legacy or high-reliability manufacturing methods utilizing through-hole technology rather than surface mount alternatives.

Replacement Considerations

Consult the official datasheet for direct pin-compatible substitutes within the same family. Verify that any alternative maintains the identical PDIP-20 package and electrical characteristics.
