TPIC6A259NE

Overview

The TPIC6A259NE is an 8-bit addressable latch featuring open-drain DMOS outputs, designed for general-purpose storage in digital systems. It operates within a logic supply voltage range of 4.5 V to 5.5 V and supports a power DMOS drain-to-source voltage up to 50 V. The device provides eight independent 350-mA outputs with short-circuit protection and includes separate power ground (PGND) and logic ground (LGND) terminals. Characterized for operation over a case temperature range of -40°C to 125°C, it utilizes a 20-pin PDIP package.

Feature Summary

• Integrates eight open-drain DMOS-transistor outputs with independent chopping current-limiting circuits for short-circuit protection
• Supports four distinct function modes: addressable latch, memory, 8-line demultiplexer, and clear
• Features separate power ground (PGND) and logic ground (LGND) terminals to minimize parasitic impedance and crosstalk

Applications

• Working registers in digital systems
• Serial-holding registers
• Decoders or demultiplexers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm the exact pin count, lead finish, and moisture sensitivity level. Ensure that the selected variant matches the required thermal resistance characteristics and operating temperature range for the intended application environment.

Selection Notes

Select this component when high-voltage switching capability combined with addressable data storage is required. The inclusion of avalanche energy tolerance and source-to-drain diode specifications makes it suitable for inductive load control applications where transient protection is necessary.

Part Context

This device belongs to the TPIC6A series of power logic addressable latches manufactured by Texas Instruments. It is characterized for industrial-grade performance and is available in both thermally-enhanced dual-in-line and wide-body surface-mount packages to accommodate various PCB layout requirements.
