HD74LV2GT245A
Dual Bus Transceivers with 3–state Outputs /
CMOS Logic Level Shifter
REJ03D0153–0200Z (Previous ADE-205-694A (Z)) Rev.2.00 Oct.23.2003
Description
The HD74LV2GT245A 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. 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.
Features
The basic gate function is lined up as Renesas uni logic series. Supplied on emboss taping for high-speed automatic mounting. TTL compatible input level. Supply
