What is 8 bit binary up counter?
The CD40193 is an 8-Bit Up/Down binary counter made by using monolithic complementary MOS (CMOS) integrated circuits. CD40193 is a part of the CD4000 IC series. Up/Down count is performed by two count inputs, one being held high while the other is clocked….CD40193 Pinout.

What is binary up-down counter?
Bidirectional counters, also known as Up/Down counters, are capable of counting in either direction through any given count sequence and they can be reversed at any point within their count sequence by using an additional control input as shown below.
What is presettable counter?
This means when the LD input is high, then whatever binary value is present on LOAD INPUTS, will be immediately copied to the outputs and stay that way until LD goes low. This enables the counter to begin from any value. , eg count from 6 to 15. Note this only works if the RESET input is low.
Which counter is used for presettable counter?
Synchronous Up/Down-Counter ICs The 74193 is a 4-bit binary up/down synchronous counter. These chips also have parallel data input leads that can be used to preset the counter.
What is a mod 8 counter?
The modulus of a counter is given as: 2n where n = number of flip-flops. So a 3 flip-flop counter will have a maximum count of 23 = 8 counting states and would be called a MOD-8 counter. The maximum binary number that can be counted by the counter is 2n–1 giving a maximum count of (111)2 = 23–1 = 710.
What is up down counter how it works?
Counters are used in many different applications. Some count up from zero and provide a change in state of output upon reaching a predetermined value; others count down from a preset value to zero to provide an output state change.
What are the applications of presettable counters?
The 74HC/HCT161 are presettable synchronous 4-bit binary counters with asynchronous reset. These devices are high speed silicon-gate CMOS devices that are pin compatible with low power Schottky TTL (LSTTL). They feature an internal look-ahead carry and can be utilized for high-speed counting.
What do you mean by presettable synchronous counters?
Presettable synchronous 4-bit binary counter; asynchronous reset. NRND. The 74LVC161 is a synchronous presettable binary counter with an internal look-head carry. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP).
How do you make a binary counter circuit?
A binary counter can be constructed from J-K flip-flops by taking the output of one cell to the clock input of the next. The J and K inputs of each flip-flop are set to 1 to produce a toggle at each cycle of the clock input.
