HD74LV21A
Dual 4-input Positive AND Gates
REJ03D0237–0300Z
(Previous ADE-205-255A (Z))
Rev.3.00
Jun. 01, 2004
Description
The HD74LV21A 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 computers), 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)
Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)
Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C)
Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V)

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.
