4502B

The 4502B is a Strobed Hex Inverter/Buffer with a common data input inhibit control and a common output disable control. The 3-state output allows common bus configurations. There are some features about 4502B as follows. First is 3-state outputs with seperate disable control. The second is common input inhibit line. Then is TTL output drive guaranteed over temperature range. The fifth of 4502B is output impedance <200 @ 5 Vdc guranteed over temperature range.

What comes next is about the recommonded operating conditions of 4502B . The VDD-VSS (DC supply voltage) is from 3 to 15 V. The operating temperature is from -55 to +125 for C and from -40 to +85 for E.

The following is about the dynamic characteristics of 4502B (CL=50 pF, TA=25). The typical TPLH (propagation delay time from data inputs) is 125 ns and the maximum is 250 ns at VDD=5 Vdc; The typical TPLH of 4502B  (propagation delay time from data inputs) is 60 ns and the maximum is 120 ns at VDD=10 Vdc; The typical TPLH (propagation delay time from data inputs) is 45 ns and the maximum is 90 ns at VDD=15 Vdc. The typical TPHL of 4502B (propagation delay time from data inputs) is 100 ns and the maximum is 200 ns at VDD=5 Vdc; The typical TPHL (propagation delay time from data inputs) is 50 ns and the maximum is 120 ns at VDD=10 Vdc; The typical TPHL (propagation delay time from data inputs) is 40 ns and the maximum is 80 ns at VDD=15 Vdc.
