TECHNICAL DATA IN74HC533A Octal 3-State Inverting Transparent Latch High-Performance Silicon-Gate CMOS The IN74HC533A is identical in pinout to the LS/ALS533. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. The data appears as the outputs in inverted form. When Latch Enable goes low, data meeting the setup and hold time becomes latched. The Output Enable input does not affect the state of the latches, but when Output Enable is high, all device outputs are forced to the highimpedance state. Thus, data may be latched even when the outputs are not enabled. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION IN74HC533AN Plastic IN74HC533ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs PIN 20=VCC PIN 10 = GND Output Output Enable Latch Enable D Q L H H L L H L H L L X no change X Z H X X = don’t care Z = high impedance Rev. 00 IN74HC533A MAXIMUM RATINGS* Symbol Parameter Value Unit -0.5 to +7.0 V VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) -1.5 to VCC +1.5 V DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V DC Input Current, per Pin ±20 mA IOUT DC Output Current, per Pin ±35 mA ICC DC Supply Current, VCC and GND Pins ±75 mA PD Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ 750 500 mW -65 to +150 °C 260 °C VOUT IIN Tstg TL Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) * Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
