CD74HC563中文资料具有三态输出的高速 CMOS 逻辑八路反向透明锁存器数据手册TI规格书

描述 Description

The ’HC533, ’HCT533, ’HC563, and CD74HCT563 are high speed Octal Transparent Latches manufactured with silicon gate CMOS technology. They possess the low power con-sumption of standard CMOS integrated circuits, as well as the ability to drive 15 LSTTL devices.
The outputs are transparent to the inputs when the latch enable (LE\\) is high. When the latch enable (LE\\) goes low the data is latched. The output enable (OE\\) controls the three-state outputs. When the output enable (OE\\) is high the outputs are in the high impedance state. The latch operation is independent of the state of the output enable.
The ’HC533 and ’HCT533 are identical in function to the ’HC563 and CD74HCT563 but have different pinouts. The ’HC533 and ’HCT533 are similar to the ’HC373 and ’HCT373; the latter are non-inverting types.
