TLC59213IN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TLC59213IN鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設(shè)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?！巴该鳌辨i存器還允許設(shè)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。

3 Description

The TLC59213 and TLC59213A are 8-bit source

drivers with input latch with CLK input and CLR to set

the output OFF. The TLC59213 and TLC59213A

have large output source currents up to 500 mA with

Darlington transistor and collectors tied to VCC. These

feature make the device optimum level of driving the

matrix of ink jet printer head, LEDs, and the scan-side

of resistor's matrix. The TLC59213 and TLC59213A

differ only in the Data Hold Time Specification (th).

The clamp diode is between output and ground for

switching inductive load.

All inputs are TTL/CMOS, which enable to any logic-

level inputs such as MCU, CPU or SN74LV594 (serial

to parallel) and the output enable LED matrix display.

It can also be used with another device sink driver

such as TLC59210, TLC59211 and TLC59212.
