HD74LV2GT157A
2-channle Multiplexer / CMOS Logic Level Shifter
REJ03D0150–0200Z
(Previous ADE-205-686A (Z))
Rev.2.00
Oct.23.2003
Description
The HD74LV2GT157A has 2–channel multiplexer in 8 pin package. 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 voltage range : 3.0 to 5.5 V
Operating temperature range : –40 to +85°C
• Logic-level translate function
3.0 V CMOS logic → 5.0 V CMOS logic (@VCC = 5.0 V)
1.8 V or 2.5 V CMOS logic → 3.3 V CMOS logic (@VCC = 3.3 V)
• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
All outputs VO (Max.) = 5.5 V (@VCC = 0 V)
• Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V)
• All the logical input has hysteresis voltage for the slow transition.
• Ordering Information
