HD74ALVC2G241 Dual Bus Buffer Noninverted with 3-state Output REJ03D0175–0200Z (Previous ADE-205-573A (Z)) Rev.2.00 Dec.18.2003 Description The HD74ALVC2G241 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. To ensure the high impedance state during power up or power down, OE should be connected to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current sinking capability of the driver. 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. • Supply voltage range : 1.2 to 3.6 V Operating temperature range: −40 to +85°C • All inputs VIH (Max.) = 3.6 V (@VCC = 0 V to 3.6 V) All outputs VO (Max.) = 3.6 V (@VCC = 0 V) • Output current ±2 mA (@VCC = 1.2 V) ±4 mA (@VCC = 1.4 V to 1.6 V) ±6 mA (@VCC = 1.65 V to 1.95 V) ±18 mA (@VCC = 2.3 V to 2.7 V) ±24 mA (@VCC = 3.0 V to 3.6 V) • Ordering Information Part Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) HD74ALVC2G241USE SSOP-8 pin TTP-8DBV US E (3,000 pcs/reel) Rev.2.00, Dec.18.2003, page 1 of 12 HD74ALVC2G241 Outline and Article Indication • HD74ALVC2G241 Index band Lot No. Y M W A 4 1 Y : Year code (the last digit of year) M : Month code W : Week code SSOP-8 Marking Function Table Inputs OE A Output Y L L L L H H H X Z OE A Output Y H L L H H H L X Z Inputs H: L: X: Z: High level Low level Immaterial High impedance Rev.2.00, Dec.18.2003, page 2 of 12 HD74ALVC2G241 Pin Arrangement OE 1 8 VCC A1 2 7 OE Y2 3 6 Y1 GND 4 5 A2 (Top view) Absolute Maximum Ratings Item Symbol Ratings Unit Supply voltage range VCC −0.5 to 4.6 V Input voltage range *1 VI −0.5 to 4.6 V VO −0.5 to VCC+0.5 V Output voltage range *1, 2 −0.5 to 4.6 Conditions Output : H or L or Z VCC : OFF Input clamp current IIK −50 mA VI < 0 Output clamp current IOK ±50 mA VO < 0 or VO > VCC Continuous output current IO ±50 mA VO = 0 to VCC Continuous current through VCC or GND ICC or IGND ±100 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 4.6 V maximum. 3.
