74ALS573BDB

The 74ALS573BDB is designed as one kind of octal transparent latch device that is functionally identical to the 74ALS373 but has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors. Features of this device are:(1)Inputs and outputs on opposite side of package allow easy interface to microprocessors; (2)Useful as an input or output port for microprocessors; (3)3-State outputs for bus interfacing; (4)Common output enable; (5)74ALS563A and 74ALS564A are inverting version of 74ALS573B and 74ALS574A respectively.

The absolute maximum ratings of the 74ALS573BDB can be summarized as:(1)Supply voltage:0.5 to +7.0 V;(2)Input voltage:0.5 to +7.0 V;(3)Input current:30 to +5 mA;(4)Voltage applied to output in High output state:0.5 to VCC V;(5)Current applied to output in Low output state: 48 mA;(6)Operating free-air temperature range:0 to +70 °C;(7)Storage temperature range: -65 to +150 °C.

The electrical characteristics of the 74ALS573BDB can be summarized as:(1)High level output voltage: 2.4 to 3.2 V;(2)Input clamp voltage: -0.73 to -1.2 V;(3)Input current at minimum input voltage: 0.1 mA;(4)High-level input current: 20 uA;(5)Off-state output current, High-level voltage applied: 20 uA;(6)Off-state output current, Low-level voltage applied: -20 uA.
