SN54AS825A 具有三态输出的 8 位总线接口触发器

These 8-bit flip-flops feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. These devices are particularly suitable for implementing multiuser registers, I/O ports, bidirectional bus drivers, and working registers.

With the clock-enable () input low, the eight D-type edge-triggered flip-flops enter data on the low-to-high transitions of the clock (CLK) input. Taking high disables the clock buffer, latching the outputs. These devices have noninverting data (D) inputs. Taking the clear () input low causes the eight Q outputs to go low independently of the clock.

Multiuser buffered output-enable (,, and ) inputs can be used to place the eight outputs in either a normal logic state (high or low logic level) or a high-impedance state
