2-channle Multiplexer
ADE-205-686 (Z)
Rev.0
May. 2002
Description
The HD74LV2GT157A has 2–channel multiplexer in 8 pin package. 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.
• TTL compatible input level.
Supply voltage range : 4.5 to 5.5 V
Operating temperature range : –40 to +85°C
• 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 ±12 mA (@VCC = 4.5 V to 5.5 V)
• All the logical input has hysteresis voltage for the slow transition.

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.
