SEMICONDUCTOR TECHNICAL DATA ! " ! High–Performance Silicon–Gate CMOS The MC74HC125A and MC74HC126A are identical in pinout to the LS125 and LS126. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC125A and HC126A noninverting buffers are designed to be used with 3–state memory address drivers, clock drivers, and other bus–oriented systems. The devices have four separate output enables that are active–low (HC125A) or active–high (HC126A). • Output Drive Capability: 15 LSTTL Loads • 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 • In Compliance with the Requirements Defined by JEDEC Standard No. 7A • Chip Complexity: 72 FETs or 18 Equivalent Gates N SUFFIX 14–LEAD PLASTIC DIP PACKAGE CASE 646–06 D SUFFIX 14–LEAD PLASTIC SOIC PACKAGE CASE 751A–03 LOGIC DIAGRAM HC125A Active–Low Output Enables A1 OE1 A2 OE2 A3 OE3 A4 OE4 2 3 HC126A Active–High Output Enables 1 2 A1 Y1 6 4 8 Y3 10 A3 11 13 Y2 8 Y3 10 11 12 A4 Y4 Y4 13 OE4 PIN 14 = VCC PIN 7 = GND FUNCTION TABLE HC125A Inputs Output HC126A Inputs Output A OE Y A OE Y H L X L L H H L Z H L X H H L H L Z 4/97 Motorola, Inc. 1997 1 Plastic SOIC TSSOP PIN ASSIGNMENT 9 OE3 12 6 4 OE2 9 MC74HCXXXAN MC74HCXXXAD MC74HCXXXADT 5 A2 Y2 ORDERING INFORMATION Y1 1 OE1 5 3 DT SUFFIX 14–LEAD PLASTIC TSSOP PACKAGE CASE 948G–01 REV 8 OE1 1 14 VCC A1 2 13 OE4 Y1 3 12 A4 OE2 4 11 Y4 A2 5 10 OE3 Y2 6 9 A3 GND 7 8 Y3 MC74HC125A MC74HC126A ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎ MAXIMUM RATINGS* Symbol VCC Parameter DC Supply Voltage (Referenced to GND) Value Unit – 0.5 to + 7.0 V Vin DC Input Voltage (Referenced to GND) – 0.5 to VCC + 0.5 V Vout DC Output Voltage (Referenced to GND) – 0.5 to VCC + 0.5 V DC Input Current, per Pin ± 20 mA Iin Iout DC Output Current, per Pin ± 35 mA ICC DC Supply Current, VCC and GND Pins ± 75 mA PD Power Dissipation in Still Air 750 500 450 mW Tstg Storage Temperature – 65 to + 150 _C TL Plastic DIP† SOIC Package† TSSOP Package† This device contains protection circuitry to guard against damage due to high static voltages or electric fields. 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. v v _C Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP, SOIC or TSSOP Package) 260 * Maximum Ratings are those values beyond which damage to the device may occur.
