MC14503B
Hex Non-Inverting 3-State
Buffer
The MC14503B is a hex non±inverting buffer with 3±state outputs, and a high current source and sink capability. The 3±state outputs make it useful in common bussing applications. Two disable controls are provided. A high level on the Disable A input causes the outputs of buffers 1 through 4 to go into a high impedance state and a high level on the Disable B input causes the outputs of buffers 5 and 6 to go into a high impedance state.
•3±State Outputs
•TTL Compatible Ð Will Drive One TTL Load Over Full Temperature Range
•Supply Voltage Range = 3.0 Vdc to 18 Vdc
•Two Disable Controls for Added Versatility
•Pin for Pin Replacement for MM80C97 and 340097

2.Maximum Ratings are those values beyond which damage to the device may occur.
3.Temperature Derating:
Plastic ªP and D/DWº Packages: ± 7.0 mW/C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high±impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.

4.Data labelled ªTypº is not to be used for design purposes but is intended as an indication of the IC's potential performance.
5.The formulas given are for the typical characteristics only at 25_C.
6.To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + (CL ± 50) Vfk
where: IT is in μA (per package), CL in pF, V = (VDD ± VSS) in volts, f in kHz is input frequency, and k = 0.006.
