SEQUENTIAL LOGIC - didactic equipment
The module can be arranged on a pair of supports for a better reading of the block diagrams and an easier use
of the connecting leads.
This module must show a schematic diagram and 2 mm terminals for the electrical connection.
The case of the module must be made in metal material.
This board allows the study of the following subjects: MSI circuits in TTL logic, synchronous and asynchronous
counters, shift registers, astable and monostable multivibrators, seven segment displays.
The board is composed of:
• 4 JK/MS flip-flop
• 2 D flip-flop
• a BCD synchronous counter
• a binary 4-bit synchronous counter
• a BCD asynchronous counter
• a binary 4-bit asynchronous counter
• 2 monostable multivibrators
• a shift register, 8-bit SI-SO
• 2 BCD 7-segment decoders
• 2 7-segment displays
• 2 BCD rotating switches
• 8 capacitors
• 2 linear potentiometers
Power supply: 5Vdc, 5W
Experiments:
PULSED CIRCUITS
Monostable multivibrator: generation of preset width
Monostable multivibrator: use of CLR input for the anticipated interruption of a pulse
Monostable multivibrator: pulse delay
