MC74LVX373 Octal D-Type Latch with 3-State Outputs With 5V−Tolerant Inputs The MC74LVX373 is an advanced high speed CMOS octal latch with 3−state outputs. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems. This 8−bit D−type latch is controlled by a latch enable input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state. http://onsemi.com SOIC−20 DW SUFFIX CASE 751D Features • • • • • • • • • High Speed: tPD = 5.8 ns (Typ) at VCC = 3.3 V Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C Power Down Protection Provided on Inputs Balanced Propagation Delays Low Noise: VOLP = 0.8 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300 mA ESD Performance: Human Body Model > 2000 V; Machine Model > 200 V These Devices are Pb−Free and are RoHS Compliant TSSOP−20 DT SUFFIX CASE 948E PIN ASSIGNMENT VCC O7 D7 D6 O6 O5 D5 D4 O4 LE 20 19 18 17 16 15 14 13 12 11 1 2 3 4 5 6 7 8 9 10 OE O0 D0 D1 O1 O2 D2 D3 O3 GND 20−Lead (Top View) MARKING DIAGRAMS 20 20 LVX 373 ALYWG G LVX373 AWLYYWWG 1 1 SOIC−20 LVX373 A WL, L Y WW, W G or G TSSOP−20 = Specific Device Code = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) PIN NAMES Pins Function OE LE D0−D7 O0−O7 Output Enable Input Latch Enable Input Data Inputs 3−State Latch Outputs ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet. © Semiconductor Components Industries, LLC, 2014 August, 2014 − Rev. 4 1 Publication Order Number: MC74LVX373/D MC74LVX373 OE LE 1 11 3 D0 2 nLE O0 Q D 4 D1 5 nLE O1 Q D 7 D2 6 nLE O2 Q D 8 D3 9 nLE O3 Q D 13 D4 12 nLE O4 Q D 14 D5 15 nLE O5 Q D 17 D6 16 nLE O6 Q D 18 D7 19 nLE O7 Q D Figure 1.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC / 8 (per latch). CPD is used to determine the no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
