Dual Bus Buffer Noninverted with 3-state Output
REJ03D0175–0200Z
(Previous ADE-205-573A (Z))
Rev.2.00
Dec.18.2003
Description
The HD74ALVC2G241 has dual bus buffer noninverted with 3-state output in an 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 Renesas 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)
