HD74ALVC2G245 Dual Bus Transceivers with 3-state Output ADE-205-641B (Z) Rev.2 Apr. 2002 Description The HD74ALVC2G245 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. 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. • 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) • Package type Package type Package code Package suffix Taping code SSOP-8 pin TTP-8DB US E (3,000 pcs / Reel) HD74ALVC2G245 Outline and Article Indication • HD74ALVC2G245 Index band Lot No. Y M W A 4 5 Y : Year code (the last digit of year) M : Month code W : Week code SSOP-8 Type No. Function Table Inputs OE DIR Operation L L B data to A bus L H A data to B bus H X Isolation H: L: X: High level Low level Immaterial Rev.2, Apr. 2002, page 2 of 11 HD74ALVC2G245 Pin Arrangement DIR 1 8 VCC A1 2 7 OE A2 3 6 B1 GND 4 5 B2 (Top view) Absolute Maximum Ratings Item Supply voltage range Input voltage range *1 Output voltage range *1, 2 Symbol Ratings Unit VCC −0.5 to 4.6 V VI −0.5 to 4.6 V VO −0.5 to VCC+0.5 V −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. The maximum package power dissipation was calculated using a junction temperature of 150°C.
