HD74LVC02 Datasheet | Hitachi Semiconductor

Description The HD74LVC02 has four 2-input NOR gates in a 14 pin package. Low voltage and high speed operation is suitable at the battery drive product (note type personal puter) and low power consumption extends the life of a battery for long time operation. Features - - - - - VCC = 2.0 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 m A (@VCC = 3.0 V to 5.5 V) Function Table Inputs A L L H H H: L: High level Low level B L H L H Output Y H L L L Pin Arrangement 1Y 1 1A 2 1B 3 2Y 4 2A 5 2B 6 GND 7 14 VCC 13 4Y 12 4B 11 4A 10 3Y 9 3B 8 3A (Top view) Absolute Maximum Ratings Item Supply voltage range Input diode current Input voltage Output diode current Symbol VCC I IK VI I OK Ratings - 0.5 to 6.0 - 50 - 0.5 to 6.0 - 50 50 Output voltage Output current VCC, GND current / pin Storage temperature VO IO I CC or IGND Tstg - 0.5 to VCC+0.5 ±50 100 - 65 to +150 Unit V m A V m A m A V m A m A °C VO = - 0.5 V VO = VCC+0.5 V VI = - 0.5 V Conditions Note: The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time.
