HD74LV20A Datasheet | Hitachi Semiconductor

Description The HD74LV20A performs the Boolean functions Y = A- B- C- D or Y = A+B + C + D in positive logic. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook puters), and the low-power consumption extends the battery life. Features - - - - - - VCC = 2.0 V to 5.5 V operation All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max.) = 5.5 V (@VCC = 0 V) Typial VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typial VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C) Output current ±6 m A (@VCC = 3.0 V to 3.6 V), ±12 m A (@VCC = 4.5 V to 5.5 V) Function Table Inputs A H L X X X B H X L X X C H X X L X D H X X X L Output Y L H H H H Note: H: High level L: Low level X: Immaterial Pin Arrangement 1A 1 1B NC 2 3 14 VCC 13 2D 12 2C 11 NC 10 2B 9 2A 8 2Y 1C 4 1D 1Y 5 6 GND 7 (Top view) Absolute Maximum Ratings Item Supply voltage range Input voltage range- 1 1, 2 Symbol VCC VI VO Ratings - 0.5 to 7.0 - 0.5 to 7.0 - 0.5 to VCC + 0.5 - 0.5 to 7.0 Unit V V V Conditions Output voltage range- Output: H or L VCC: OFF Input clamp current Output clamp current Continuous output current Continuous current through VCC or GND Maximum power dissipation at Ta = 25°C (in still air)- 3 I IK I OK IO I CC or IGND PT - 20 ±50 ±25 ±50 785 500 m A m A m A m A m W VI < 0 VO < 0 or VO > VCC VO = 0 to VCC SOP TSSOP Storage temperature Tstg - 65 to 150 °C Notes: 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. 1. The input and output voltage ratings may be exceeded even if the input and output clamp-current ratings are observed. 2. This value is limited to 5.5 V maximum. 3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
