CD4510BE - 4-Bit CMOS BCD Up/Down Counter | TI
部品番号: CD4510BE ✓ 生産中CD4510BE 概要
A BCD counter is a digital counter that represents each decimal digit with four binary bits. The CD4510BE counts upward through 0 to 9 or downward through 9 to 0, making it useful when a system must operate in a decimal format rather than a free-running 4-bit binary sequence. Within the broader hierarchy, it is a counter and divider within CMOS logic ICs, supporting sequencing, timing, and control functions.
The device provides medium-speed operation with a typical clock frequency of 8 MHz at a 10 V supply. Its supply-voltage tolerance allows operation across 3 V to 18 V, while the CD4000-series CMOS architecture provides low static power use relative to many older bipolar counter families. Preset and reset inputs allow a designer to load an initial BCD value or clear the counter independently of its clock-driven count sequence.
Internally, the counter uses four synchronously clocked D-type flip-flops with gating arranged to provide T-type flip-flop operation. Four decoded Q outputs and four complementary Q outputs expose the current decade digit. The carry and complementary carry outputs indicate decimal overflow or underflow, allowing multiple CD4510BE devices to form cascaded decimal counting stages without decoding every intermediate value.
Typical applications include decade counters, digital clocks and timers, industrial sequencing equipment, test and measurement systems, and control panels that need a decimal display count. The decoded outputs can drive display drivers or logic, while the carry output provides a natural boundary event for incrementing another counter stage.
Designers should account for the asynchronous nature of the reset and preset controls, provide clean power and ground connections, and use suitable decoupling close to the device. Clock-edge requirements and signal transition timing must be checked against the operating voltage because permissible clock rates vary with supply voltage.
This page combines the manufacturer specifications, package details, cross-reference alternatives, application guidance, and practical design considerations needed to evaluate the CD4510BE as a 16-pin CMOS BCD up/down counter.

主な用途
CD4510BE の用途: 6 件s: Digital Clock and Timer Decades, Industrial Sequencing and Preset Stations, Cascaded Decimal Counter, Test and Measurement Counters, Control Panel and Selector Positions, Legacy Embedded Control Logic.
Digital Clock and Timer Decades
The CD4510BE fits a decimal clock or timer because it counts from 0 through 9 and exposes decoded Q outputs for the active digit. Its active-high preset input can load an initial value, while the active-high reset input clears the count independently of the clock. With a typical operating frequency of 8 MHz at 10 V, the device provides ample timing margin for conventional display-decoder and switch-debounce circuits operating at much lower clock rates.
おすすめ
Industrial Sequencing and Preset Stations
In an industrial sequencing station, the CD4510BE can count a repeatable series of positions or process steps and provide a carry event when a decade completes. Its four decoded outputs allow control logic to detect the current count directly, avoiding a binary-to-BCD conversion stage. The 3 V to 18 V operating range supports legacy industrial logic, while preset and reset provide deterministic initialization at the start of each operating cycle.
おすすめ
Cascaded Decimal Counter
Multiple CD4510BE devices can form a cascaded decimal counter by connecting one stage's carry output to the next stage's clock input. The target's decoded decade outputs allow each digit to be handled independently, and the carry output marks the 9-to-0 rollover used to increment the next digit. This architecture is useful for panel meters, event counters, and legacy timing systems that need more than one decimal digit.
おすすめ
Test and Measurement Counters
The CD4510BE can serve as a measurement-count decade in laboratory and service equipment that accumulates events in decimal form. Each clock pulse advances the count, while the decoded outputs identify the current digit and the carry output provides a convenient event boundary. The device's typical 8 MHz operation at 10 V allows it to handle substantially faster event rates than are normally required in human-readable measurement counters.
おすすめ
Control Panel and Selector Positions
A CD4510BE can track ten discrete selector or command positions and present the active position through decoded outputs. Preset lets the circuit jump to a known command state, while reset returns the counter to zero without waiting for a clock sequence. This makes the part useful in legacy control panels, rotary selector interfaces, and step-command generators where decade rollover must correspond directly to a physical control action.
おすすめ
Legacy Embedded Control Logic
The CD4510BE is suitable for adding decimal sequencing to an older CMOS control design without a programmable microcontroller. Four D-type flip-flops with T-type gating implement the count, while parallel preset and reset controls support deterministic state loading. Because the device operates from 3 V to 18 V, it can bridge systems built around 5 V, 10 V, or 15 V CMOS logic, subject to the exact timing and output limits for the selected supply voltage.

設計ノート
Place the supply bypass capacitor immediately between the CD4510BE VDD and GND pins, with the ground return kept short to reduce clock noise and output switching transients. Because the device supports a 3 V to 18 V range, verify the timing limits, input levels, and output drive at the actual supply voltage rather than assuming performance from the 8 MHz typical figure at 10 V.
Treat RESET, PRESET, and UP/DN as asynchronous control signals. Keep them away from the CLK trace, provide a defined inactive level, and remove switch bounce before it reaches a counter input. A preset or reset pulse must satisfy the manufacturer's setup and hold timing at the selected supply voltage; otherwise the decoded Q outputs may change unexpectedly during a clock transition.
For a cascaded decimal counter, route each stage's CARRY output directly to the next stage's CLK input and keep the path short. The CARRYB output is available when the following stage requires an active-low clock. Preserve the physical 16-pin PDIP footprint and pin numbering when using a replacement; a functionally similar binary counter is not a valid substitute because its state range and rollover behavior differ.
Do not confuse the CD4510 BCD decade counter with the CD4516 binary up/down counter. The CD4510BE advances through ten decimal states and produces a carry at the decade boundary, whereas a binary counter advances through sixteen states. Check the UP/DN polarity, decoded versus complementary outputs, and active-high asynchronous control levels against the manufacturer pin-description table.
コンプライアンス情報
The CD4510BE is a legacy CMOS logic IC rather than an automotive-qualified device. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from the current manufacturer product documentation or declaration.
