HD74ALVC1G240
Bus Buffer Inverted with 3-state Output
ADE-205-619A (Z)
Rev. 1
July. 2001
Description
The HD74ALVC1G240 has a bus buffer inverted with 3-state output in a 5 pin package. Output is disabled
when the associated output enable (OE) input is high. To ensure the high impedance state during power up
or power down,
OE
should be connected to V
CC
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.

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.
