HD74ALVC2G241
Dual Bus Buffer Noninverted with 3-state Output
ADE-205-573 (Z)
Rev.0
July. 2001
Description
The HD74ALVC2G241 has dual bus buffer noninverted with 3-state output in a 8 pin package. Two
noninverters are included in one circuit. Each circuit can be independently controlled by the enable signal
OE or OE, which enables outputs when receiving a low or high level signal, respectively. To ensure the
high impedance state during power up or power down, OE should be connected to VCC through a pull-up
resistor; the minimum value of the resistor is determined by the current sinking capability of the driver.
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
• The basic gate function is lined up as hitachi uni logic series.
• Supplied on emboss taping for high speed automatic mounting.
• Supply voltage range : 1.2 to 3.6 V
Operating temperature range : −40 to +85°C
• All inputs VIH (Max.) = 3.6 V (@VCC = 0 V to 3.6 V)
All outputs VO (Max.) = 3.6 V (@VCC = 0 V)
• Output current
±2 mA (@VCC = 1.2 V)
±4 mA (@VCC = 1.4 V to 1.6 V)
±6 mA (@VCC = 1.65 V to 1.95 V)
±18 mA (@VCC = 2.3 V to 2.7 V)
±24 mA (@VCC = 3.0 V to 3.6 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 if the input and output clamp-current
ratings are observed.
2. This value is limited to 4.6 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
