The SN54390 monolithic circuit contains eight master-slave flip-flops and additional gating to implement.It incorporates dual divide-by-two and divide-by-five counters, which can be used to implment cycle lengths equal to any whole and/or cumulative multiples of 2 and/or 5 up to divide-by-100.
Features of of the SN54390 are:(1)dual versions of the popular; (2)dual 4-bit binary counter with individual clocks; (3)has direct clear for each 4-bit counter; (4)dual 4-bit versions can significantly improve system densities by reducing counter package count by 50%; (5)typical maximum count frequency: 35 MHz; (6)buffered outputs reduce possibility of collector communication.
The absolute maximum ratings of the SN54390 can be summarized as:(1): supply voltage, vcc is 7 V ; (2): input voltage is 5.5 V; (3): storage temperature range is -65 to 150;(4): operating free-air temeprature range is -55 to 125.

The SN5439 contains four independent 2-input NOR buffer gates with open-collector outputs.Open-collector outputs require resistive pull-up resistors to perform correctly. It may be connected to other open-collector outputs to implement active-low wired-OR or...
The SN5438 contains four independent 2-input NOR buffer gates with open-collector outputs.Open-collector outputs require resistive pull-up resistors to perform logically but can deliver high VOH levels and are commonly used in wired-AND applications.It is ch...
The SN54376 quadruple TTL J-K flip-flop incorporates a number of third-generation IC features that can simplify system design and reduce flip-flop package count by as much as design and reduce flip-flop package count by as much as 50%.It features hysteresis ...
The SN54365A Hex buffer and line driver is designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers and bus oriented receivers and transmitters.the designer has choice of selected combinations of ...
The SN54351 is designed as one kind of dual data selector / multiplexer with 3-state outputs. Symmetricaly switching, complementary decode generators minimize decoder skew during changes at the select inputs and ensure that potentially erroneous effects are ...
