| DM74LS573 Octal D-Type Latch with 3-STATE Outputs October 1988 Revised March 2000 DM74LS573 Octal D-Type Latch with 3-STATE Outputs General Description The DM74LS573 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 DM74LS373, but has different pinouts. Features s Inputs and outputs on opposite sides of package allowing easy interface with microprocessors s Useful as input or output port for microprocessors s Functionally identical to DM74LS373 s Input clamp diodes limit high speed termination effects s Fully TTL and CMOS compatible Ordering Code: Order Number DM74LS573WM DM74LS573N Package Number M20B N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation.
