Since CMOS transmission gate 78 is conductive, the output signal of NAND gate 72 is applied to NAND gates 82 and 86. NAND gate 86 now functions as an inverter. Therefore, NAND gates 82 and 88 receive address signal bits complementary to each other at their respective one inputs. After ...
(storing means) constituted of NAND gates NA03 and NA04, and which of the control signal group of the Intel-type CPU or the control signal group of the Motorola-type CPU has been inputted is recognized on the basis of the contents of the latch, and when the control signal group of ...
means responsive to the determinations of the relative magnitudes of the input voltage and the reference voltages in the plurality for indicating the magnitude of the input voltage. 8. In a combination as set forth in claim 7, the indicating means including a plurality of "nand" networks each ...
A line 99 enables selection of unipolar or bipolar operation by means of a power switch 96 and NAND gates 27a. 28a and 29a. In an extra measure of efficiency, the apparatus includes a commutation delay timing circuit 95 for ... DH Peters,J Harth 被引量: 0发表: 1991年 ...
PURPOSE:To facilitate the conversion of clock frequecy with a simple circuit, by using two NAND gates, a specific frequency and a clock signal of an integer-fold level of frequency compared with said specific frequency. CONSTITUTION:A clock signal of frequency f is supplied to an input ...
When a 0 bit is stored in the first flip-flop simultaneously with a 1 bit being stored in the second flip-flop, no output pulses is produced by the second NAND gate. The output pulses produced by the two NAND gates are converted to an output signal, representing a double density encoded...

Main scanning-direction and subscanning-direction clock pulses CKm and CKs are sent to NAND gates 31a-31d through counters 27 and 29 and the decoders 28 and 30, and outputs Ga-Gd load a signal DOR through a gate 34 when the last picture signal is loaded on the FF23-9. Consequently,...
circuit are always 1 due to the logical condition of NAND gates 26 and 27 independently of logical values of signals phi1 and phi2, and gates 14 and 17 are always connected, and the same data as input line 1 is outputted to output line 18, thus making the FF into a combinatorial ...
" as is the input line 9108a to NAND gate 9108. Due to the action of inverter 9105, input line 9106b is always "down" as is input line 9106a during the period of scan. Consequently, during any one line scan, with switch 9100 in its "white" position, the output of NOR gate 9106...
