HD74LVC16541

HD74LVC16541 16-bit Buffers / Line Drivers with 3-state Outputs ADE-205-058B(Z) Rev.2 September 1995 Description The HD74LVC16541 has sixteen buffers with three state outputs in a 48 pin package. When G1 and G 2 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) 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 HD74LVC16541 Pin Arrangement 1G1 1 1Y1 2 1Y2 3 GND 4 1Y3 5 1Y4 6 VCC 7 1Y5 8 1Y6 9 GND 10 1Y7 11 1Y8 12 2Y1 13 2Y2 14 GND 15 2Y3 16 2Y4 17 VCC 18 2Y5 19 2Y6 20 GND 21 2Y7 22 2Y8 23 2G1 24 48 1G2 47 1A1 46 1A2 45 GND 44 1A3 43 1A4 42 VCC 41 1A5 40 1A6 39 GND 38 1A7 37 1A8 36 2A1 35 2A2 34 GND 33 2A3 32 2A4 31 VCC 30 2A5 29 2A6 28 GND 27 2A7 26 2A8 25 2G2 (Top view) 2 HD74LVC16541 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 Output current VCC, GND current / pin Storage temperature VO IO I CC or IGND Tstg –0...
