ETC HD74ALVC2G245

HD74ALVC2G245
Dual Bus Transceivers with 3-state Output
ADE-205-641B (Z)
Rev.2
Apr. 2002
Description
The HD74ALVC2G245 has two buffers with three state output in a 8 pin package. When DIR is high, data
is transferred from the A inputs to the B outputs, and when DIR is low, data is transferred from the B inputs
to the A outputs. The A and B buses are separated by making the enable input (OE) high level. 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.
