Description

The invention relates to a pulse technique and can be used in microelectronics in the synthesis of computing devices.

Known electronic pulse key, made of transistors and ⁵ tunnel diodes SP The disadvantage of the known technical solution is low reliability.

The closest technical solution to the invention is an electronic pulse key containing a symmetric trigger with multi-emitter transistors in feedback circuits [2].

A disadvantage of the known technical solution is its complexity.

The purpose of the invention is to simplify the electronic pulse key.

The goal is achieved by the fact that _m electronically pulsed manner, comprising first and second Transistor · ^ ry whose emitters are connected with each other, 'and SW2 are connected to the collectors

Electronic pulse key works as follows.

the level of the logical unit (high voltage level), transistors 1 and 2 are closed, on the output buses 16, 17 - the level of the logs. chesky ^ 'yujnitsy.' ".......

Suppose that, in the initial state, there is a logic zero level on the control bus 14, and a logic unit level on the control bus 15. When this transistor 3 is opened, the rest of all transistors are closed.

The logical zero level applied to the switching input 13 opens the transistor 2 and enters the output bus 17. Transistor 1 cannot open, because its base-emitter junction is shunted by the open transistor 3. When the logical Zero level appears on the collector of transistor 2, transistor 6 opens shunting at the same time the base-emitter transition of the transistor 4, preventing it from turning on when a level of logical zero appears on the control bus 15 during the Impulse action on the switching bus. Occurrences of the level of the logical unit on the bus 14 of the control of the switch will also not change the key state, since transistor 3 remains open.F.m, - ^ alNcho ^ urtja'albteyogo 'zero on the collector of transistor 2.
