74AC573 • 74ACT573 Octal Latch with 3-STATE Outputs November 1988 Revised October 1999 74AC573 • 74ACT573 Octal Latch with 3-STATE Outputs General Description The 74AC573 and 74ACT573 are high-speed octal latches with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. The 74AC573 and 74ACT573 are functionally identical to the 74AC373 and 74ACT373 but with inputs and outputs on opposite sides. Features s ICC and IOZ reduced by 50% 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 74AC373 and 74ACT373 s 3-STATE outputs for bus interfacing s Outputs source/sink 24 mA s 74ACT573 has TTL-compatible inputs Ordering Code: Order Number 74AC573SC 74AC573SJ 74AC573MTC 74AC573PC 74ACT573SC 74ACT573SJ 74ACT573MTC 74ACT573PC Package Number M20B M20D MTC20 N20A M20B M20D MTC20 N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS--013, 0.300” Wide Body 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS--013, 0.300” Wide Body 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Device also available in Tape and Reel.

When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D-type input changes. When LE is LOW the latches store the information that was present on the D-type inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-STATE buffers are controlled by the Output Enable (OE) input. When OE is LOW, the buffers are enabled. When OE is HIGH the buffers are in the high impedance mode but this does not interfere with entering new data into the latches. Truth Table Inputs OE L L L H H = HIGH Voltage L = LOW Voltage Z = High Impedance X = Immaterial O0 = Previous O0 before HIGH-to-LOW transition of Latch Enable Outputs D H L X X On H L O0 Z LE H H L X Logic Diagram Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. www.fairchildsemi.com 2 74AC573 • 74ACT573 Absolute Maximum Ratings(Note 1) Supply Voltage (VCC) DC Input Diode Current (IIK) VI = −0.5V VI = VCC + 0.5V DC Input Voltage (VI) DC Output Diode Current (IOK) VO = −0.5V VO = VCC + 0.5V DC Output Voltage (VO) DC Output Source or Sink Current (IO) DC VCC or Ground Current per Output Pin (ICC or IGND) Storage Temperature (TSTG) Junction Temperature (TJ) (PDIP) 140°C ±50 mA −65°C to +150°C ±50 mA −20 mA +20 mA −0.5V to VCC + 0.5V −20 mA +20 mA −0.5V to VCC + 0.5V −0.5V to +7.0V Recommended Operating Conditions Supply Voltage (VCC) AC ACT Input Voltage (VI) Output Voltage (VO) Operating Temperature (TA) Minimum Input Edge Rate (∆V/∆t) AC Devices VIN from 30% to 70% of VCC VCC @ 3.0V, 4.5V, 5.5V ACT Devices VIN from 0.8V to 2.0V VCC @ 4.5V, 5.5V 125 mV/ns Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur.
