The ’LS573 is a high speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. This device is functionally identical to the ’LS373, but has different pinouts.

Features :-

• Inputs and outputs on opposite sides of package allowing easy interface with microprocessors
• Useful as input or output port for microprocessors
• Functionally identical to ’LS373
• Input clamp diodes limit high speed termination effects
• Fully TTL and CMOS compatible

Specifications :-

• Supply Voltage : 4.75 to 5.25V
• High Level Input Voltage : 2V
• Low Level Input Voltage : 0.8V
• High Level Input Current : -2.6V
• Low Level Output Current : 24V
• Free Air Operating Temperature : 70˚C

Package Includes :-

1 X 74LS573 IC - (SMD Package) - 3-State Octal D-Type Latch IC (74573 IC)
