74LVTH373集成電路（IC）的鎖存器規(guī)格書PDF中文資料

74LVTH373屬于集成電路（IC）的鎖存器。由安森美半導(dǎo)體公司制造生產(chǎn)的74LVTH373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。“透明”鎖存器還允許設(shè)備輸出在鎖存使能信號有效時反映輸入的當(dāng)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。

General Description

The LVT373 and LVTH373 consist of eight latches with 3-STATE outputs for bus organized system applications. The latches appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data satisfying the input timing requirements is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in a high impedance state.

Features

■ Input and output interface capability to systems at 5V VCC

■ Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH373), also available without bushold feature (74LVT373)

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free bus loading

■ Outputs source/sink –32 mA/+64 mA

■ Functionally compatible with the 74 series 373

■ ESD performance:

– Human-body model > 2000V

– Machine model > 200V

– Charged-device model > 1000V
