40193 IC 4-Bit Binary Up/Down Counter

40193 IC 4-Bit Binary Up/Down CounterThe CD40193BE is a synchronous 4-bit binary up/down counter IC built using CMOS technology. Designed to offer high-speed performance with low power consumption, this IC is ideal for applications requiring reliable digital counting in both upward and downward directions. Unlike asynchronous counters, the CD40193 updates all outputs simultaneously on the clock edge, ensuring glitch-free operation and precise timing.It features separate Up and Down clock inputs, along with parallel load capability, allowing preloading of any 4-bit binary value using the preset inputs. It also includes carry and borrow outputs for cascading multiple counters. The device supports a wide operating voltage range and is pin-compatible with TTL logic families, making it versatile in mixed-signal systems.Key FeaturesSynchronous counting on both up and down edgesSeparate Up and Down Clock InputsParallel Load Capability for Preloading CountCarry and Borrow Outputs for cascadingTTL-compatible inputs and outputsWide supply voltage range: 3V to 15VDIP-16 package for easy PCB integrationProduct SpecificationsSpecificationValueProfessional NameCD40193BEFunction4-bit Binary Up/Down CounterLogic FamilyCMOSCounter TypeSynchronousInput Clock SignalsUp Clock (CPU), Down Clock (CPD)Preset InputsYes (P0–P3)Supply Voltage Range3V to 15VOutput TypeBuffered CMOSPropagation Delay~200 ns @ 10VPackageDIP-16                   ‘Operating Temp Range-55°C to 125°CPin Configuration (DIP-16)Pin No.SymbolDescription1CPDClock Pulse Down (Down Count Input)2CPUClock Pulse Up (Up Count Input)3P0Parallel Data Input Bit 04P1Parallel Data Input Bit 15P2Parallel Data Input Bit 26P3Parallel Data Input Bit 37PEParallel Enable (active low)8GNDGround9Q3Output Bit 3 (MSB)10Q2Output Bit 211Q1Output Bit 112Q0Output Bit 0 (LSB)13TCUPTerminal Count Up (Carry Output)14TCDOWNTerminal Count Down (Borrow Output)15CETCount Enable T (active high)16VDDSupply VoltageApplicationsDigital counters and frequency dividersEvent counters (up/down)Position encodersTimers and sequencing circuitsClock division in digital logic systemsLearning and training kits for digital electronics
