TPIC6B273N

Overview

The TPIC6B273N is an octal D-type latch manufactured by Texas Instruments, housed in a 20-pin PDIP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum output voltage of 50 V. The device provides an output current capability of 150 mA with a propagation delay of 150 ns. It features positive edge triggering and inverting polarity, consuming 150 μA of supply current while delivering a high-level output current of -1 μA.

Feature Summary

• Octal configuration providing eight independent D-type latches for parallel data handling
• High-voltage output capability supporting up to 50 V load connections
• Positive edge-triggered clocking mechanism for precise timing control
• Robust output drive strength suitable for direct interfacing with external loads

Applications

• Parallel-to-serial data conversion circuits
• Memory buffer stages in digital systems
• Output port expansion for microcontroller interfaces
• Latching mechanisms in industrial control panels

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the package type matches the required 20-pin DIP form factor. Ensure the operating temperature range aligns with the specified -40 °C to 125 °C limits for your application environment. Cross-reference the logic family characteristics to guarantee compatibility with existing system voltage levels.

Selection Notes

Select this component when an octal latch with high-voltage tolerance is required. Consider the 150 mA output current for driving moderate loads directly. Evaluate the 150 ns propagation delay against system timing constraints. Verify that the through-hole mounting style fits the PCB layout requirements. Compare power consumption needs against the 150 μA supply current specification.

Part Context

This part belongs to the TPIC series of high-voltage shift registers and latches from Texas Instruments. It complements other devices in the family by offering specific latching functionality rather than shifting. The PDIP-20 package ensures compatibility with standard breadboards and through-hole manufacturing processes. It serves as a bridge between low-voltage logic and higher-voltage actuation or display elements.

Replacement Considerations

Consult official substitution guides for equivalent octal latches with matching voltage ratings. Verify pinout compatibility before swapping with similar components from other manufacturers. Ensure that any alternative part maintains the same 50 V output voltage limit and 150 mA current capacity.
