7476 is a kind of positive edge triggered flip flop with individual J-K, clock, preset, and clear inputs. The J-K input is loaded into the master while the clock is high and transferred to the slave on the high to low transition. the J and K inputs must be stable when the clock is high. It features 16ns input Rise time at 5V, 25ns input Fall time at 5V, Min high level input voltage 2V, Max low level input voltage 0.8V.
This post is mainly to introduce the 7476 pinout and 7476 circuit diagram for your demands.
7476 has 16 pins, and each pin has individual usage to make the whole chip achieve its function.
The 7476 pinout can be found in the picture below:
also the pin configurations for 7476 are labeled already.
|Pin Number||Pin Name||Description|
|5||Vcc||Powers the IC typically with 5V|
|13||Ground||Connected to the ground of the system|
|JK Flip Flop – 1 / JK Flip Flop - 2|
|1,6||Clock-1/ Clock-2||These pins must be provided with clock pulse for the flip flop|
|2,7||Preset-1 / Preset-2||When Preset is high the flip flop will set Q=1 and not Q=0|
|3, 8||Clear-1/Clear-2||When Clear is high the flip flop will set Q=0 and not Q=1|
|12,16||K-1/ K-2||Input pin of the Flip Flop|
|4,9||J-1 / J-2||Another Input pin of the Flip Flop|
|10,14||Q-1(bar) / Q-2 (bar)||Inverted output pin of Flip Flop|
|11,15||Q-1 / Q-2||Output Pin of the Flip Flop|
7476 circuit schematic
A circuit schematic can better help us to understand circuits and components used, and it's a reference to make the actual circuit work.
Below is a fully labeled 7476 schematic diagram for reference.
Referring to 7476 Features, the first scene we can think is that it works as DUAL JK flip flop chip.
Except that one, there still have some other features and applications we may need to know, which can help us to make use of it well, like utilizing as shift registers, Memory / control registers, EEPROM circuits, latching devices, operating voltage from 4.5v to 5.5v, available in 14 pin PDIP, GDIP, PDSO packages.
