Dual Bus Buffer Noninverted with 3–state Output /
CMOS Logic Level Shifter

Description
The HD74LV2GT241A 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. The input
protection circuitry on this device allows over voltage tolerance on the input, allowing the device to be used
as a logic–level translator from 3.0 V CMOS Logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to
3.0 V CMOS Logic while operating at the high-voltage power supply. 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.

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.
