CD74HCT563M
TEXAS INSTRUMENTS CD74HCT563M 芯片, 74HCT 逻辑器件
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.
