Description

The SN74LV573ADWE4 is one member of the SN74LV573A series.These devices feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. This device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs.

Features of the SN74LV573ADWE4 are:(1)2-V to 5.5-V VCC operation; (2)Max tpd of 8 ns at 5 V; (3)support mixed-mode voltage operation on all ports; (4)Ioff Supports partial-power-down mode operation;(5)latch-up performance exceeds 250 mA per JESD 17.To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.These devices are fully specified for partial-power-down applications using Ioff.The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.

The absolute maximum ratings of the SN74LV573ADWE4 can be summarized as:(1)supply voltage range:-0.5 to 7.0V;(2)input voltage range:-0.5 to 7.0V;(3)output voltage range applied in the high or low state:-0.5 to Vcc+0.5V;(4)input clamp current:-20mA; (5)output clamp current:-50mA; (6)voltage range applied to any output in the high-impedance or power-off state:-0.5 to 7.0V; (7)storage temperature range:-65 to 150.Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.The information provided on this page represents TI's knowledge and belief as of the date that it is provided.
