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 — 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 “P and D/DW” Packages: – 7.0 mW/_C From 65_C T o 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, V

and V

out

should be constrained

to the range V

v (Vin or V

out

) v VDD.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either V

or VDD). Unused outputs must be left open.

4. Data labelled “Typ” 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: I

T(CL

) = IT(50 pF) + (CL – 50) Vfk

where: I

is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.006.
