MC14503B_11 Datasheet, PDF (1/7 Pages) ON Semiconductor – Hex Non-Inverting 3-State Buffer

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.
Features
• 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
• These Devices are Pb−Free and are RoHS Compliant

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. Maximum Ratings are those values beyond which damage to the device may
occur.
2. Temperature Derating:
Plastic “P and D/DW” 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, V_in and V_out should be constrained
to the range V_SS v (V_in or V_out) v V_DD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V_SS or V_DD). Unused outputs must be left open.
