HD74LVC541A

HD74LVC541A Octal Buffers / Line Drivers with 3-state Outputs ADE-205-115B(Z) 3rd Edition December 1996 Description The HD74LVC541A has eight line drivers with three state outputs in a 20 pin package. When G1 and G2 is low level, this drivers set up output is enable. Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features VCC = 2.0 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (Max.) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@VCC = 3.0 V to 5.5 V) Function Table Inputs G1 L L H X H: L: X: Z: High level Low level Immaterial High impedance G2 L L X H A L H X X Output Y L H Z Z HD74LVC541A Pin Arrangement G1 1 A1 A2 2 3 20 VCC 19 G2 18 Y1 17 Y2 16 Y3 15 Y4 14 Y5 13 Y6 12 Y7 11 Y8 A3 4 A4 A5 A6 A7 5 6 7 8 A8 9 GND 10 (Top view) 2 HD74LVC541A Absolute Maximum Ratings Item Supply voltage Input diode current Input voltage Output diode current Symbol VCC I IK VI I OK Ratings –0.5 to 6.0 –50 –0.5 to 6.0 –50 50 Output voltage VO –0.5 to VCC +0.5 –0.5 to 6.0 Output current VCC, GND current / pin Storage temperature IO I CC or IGND Tstg ±50 100 –65 to +150 Unit V mA V mA mA V V mA mA °C VO = –0.5 V VO = VCC+0.5 V Output "H" or "L" Output "Z" or VCC:OF...
