HD74LV240A
Octal Buffers / Drivers with 3-state Outputs
ADE-205-272 (Z)
1st Edition
April 1999
Description
The HD74V240A has eight inverter drivers with three-state outputs in a 20-pin package. Four inverters are
included in one circuit. Each circuit can be independently controlled by the enable signal 1OE or 2OE,
which enables outputs when receiving a low-level signal. Low-voltage operation is suitable for 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 ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 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.
