HD74LV2GT157A 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. • Package type Package type Package code Package suffix Taping code SSOP-8 pin TTP-8DB US E (3,000 pcs / Reel) HD74LV2GT157A Outline and Article Indication • HD74LV2GT157A Index band Lot No. Y M W T 5 7 Y : Year code (the last digit of year) M : Month code W : Week code SSOP-8 Type No. Function Table Inputs Outputs STB SEL A B Y Y H X X X L H L L L X L H L L H X H L L H X L L H L H X H H L H : High level L : Low level X : Immaterial Rev.0, May. 2002, page 2 of 10 HD74LV2GT157A Pin Arrangement A 1 8 VCC B 2 7 STB Y 3 6 SEL GND 4 5 Y (Top view) Rev.0, May. 2002, page 3 of 9 HD74LV2GT157A Absolute Maximum Ratings Item Supply voltage range Input voltage range *1 Output voltage range *1, 2 Symbol Ratings Unit VCC –0.5 to 7.0 V VI –0.5 to 7.0 V VO –0.5 to VCC + 0.5 V –0.5 to 7.0 Test Conditions Output : H or L VCC : OFF Input clamp current IIK –20 mA VI < 0 Output clamp current IOK ±50 mA VO < 0 or VO > VCC Continuous output current IO ±25 mA VO = 0 to VCC Continuous current through VCC or GND ICC or IGND ±50 mA Maximum power dissipation *3 at Ta = 25°C (in still air) PT 200 mW Storage temperature Tstg –65 to 150 °C 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.
