HD74LV540A
Octal Inverted Buffers / Drivers with 3-state Outputs

Description
The HD74LV540A has eight inverter drivers with three state outputs in a 20 pin package. When
OE1
and
OE2
is low
level, this drivers set up output is enable. Low-voltage operation is suitable for battery-powered products (e.g.,
notebook computers), and the low-power consumption extends the battery life.

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 5.5 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
