HD74ALVC2G126
Dual Bus Buffer with 3-state Output
REJ03D0172–0200Z (Previous ADE-205-622A (Z))
Rev.2.00 Dec.18.2003
Description
The HD74ALVC2G126 has dual bus buffer with 3-state output in an 8 pin package. Output is disabled when the associated output enable (OE) input is low. To ensure the high impedance state during power up or power down, OE should be connected to GND through a pull-down resistor; the minimum value of the resistor is determined by the current souring 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) • Ordering Information

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.
