IC 74HCT573 Tri-State Octal D-type Transparent Latch
IC 74HCT573 Tri-State Octal D-type Transparent Latch, Tri State Octal D Type Transparent LatchSpecificationsThe MM74HCT573 octal D-type latches and MM74HCT574 octal D-type flip-flop advanced silicon-gate CMOS technology, which provides the inherent benefits of low power consumption and wide power supply range, but are LS-TTL input and output characteristic and pin-out compatible. The 3-STATE outputs are capable of driving 15LS-TTL loads. All inputs are protected from damage due to static discharge by internal diodes to VCC and ground. When the MM74HCT573 Latch Enable input is HIGH, theQ outputs will follow the D inputs. When the Latch Enable goes LOW, data at the D inputs will be retained at the outputs until Latch Enable returns HIGH again. When a high logic level is applied to the Output Control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.Features TTL input characteristic compatible Typical propagation delay: 18 ns Low input current: 1 mA maximum Low quiescent current: 80 mA maximum Compatible with bus-oriented systems Output drive capability: 15 LS-TTL loads
