Title: Ttl logical circuit
Inventor: SUZUKI HIROICHI
IPC: H03K19/088
Filed: 1981-11-30
Abstract: PURPOSE:To keep assuredly an output state obtained immediately after supplying power to a TTL circuit at H level, by connecting a delaying circuit between a power supply and a base of switching transistor which turned on and off in response to an input signal. CONSTITUTION:It is hardly acceptable for a set gate SG that an output OUT is set at L even if temporarily at power supply. The set input SET in the initial state is usually set at H level at the power supply in order to prevent the undesired current from flowing to a thermal head. Howver, the input SET generally has a rise with a slight delay along with the rise of the power supply Vcc. Thus the diodes D1-Dn are inserted in series to a resistance RS to prevent the output of L level which is produced when power is supplied. As a result, a phase split TRQ1 is forcibly kept off until the voltage Vcc rises up to a certain level to prevent an input TRQ1 from being turned on and the OUT from being set at L level.
