TPIC6273DWG4屬于集成電路（IC）的鎖存器。由美國德州儀器公司制造生產(chǎn)的TPIC6273DWG4鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變。“透明”鎖存器還允許設備輸出在鎖存使能信號有效時反映輸入的當前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。

description

The TPIC6273 is a monolithic high-voltage

high-current power logic octal D-type latch with

DMOS transistor outputs designed for use in

systems that require relatively high load power.

The device contains a built-in voltage clamp on the

outputs for inductive transient protection. Power

driver applications include relays, solenoids, and

other medium-current or high-voltage loads.

The TPIC6273 contains eight positive-edgetriggered

D-type flip-flops with a direct clear input.

Each flip-flop features an open-drain power

DMOS transistor output.

When clear (CLR) is high, information at the D

inputs meeting the setup time requirements is

transferred to the DRAIN outputs on the positivegoing

edge of the clock pulse. Clock triggering

occurs at a particular voltage level and is not

directly related to the transition time of the

positive-going pulse. When the clock input (CLK)

is at either the high or low level, the D input signal

has no effect at the output. An asynchronous CLR

is provided to turn all eight DMOS-transistor

outputs off.

The TPIC6273 is characterized for operation over

the operating case temperature range of –40°C

to 125°C.
