Product details
Overview
ICM7217BIPI from Maxim Integrated is a 4-digit BCD counter/decoder/driver IC with built-in multiplexed 7-segment LED display control, operating from 4.5V to 5.5V supply, featuring 500kHz maximum clock frequency and internal 100kΩ pull-up resistors on segment drivers, used in digital panel meters and industrial readouts.
For engineers reviewing the ICM7217BIPI datasheet, ICM7217BIPI pinout, ICM7217BIPI application, or ICM7217BIPI equivalent, key selection criteria include its integrated BCD decoding, common-anode LED drive capability, on-chip multiplexing control, and compatibility with 4-digit static or multiplexed displays in cost-sensitive instrumentation designs.
Technical Context
The ICM7217BIPI integrates a 4-digit BCD counter, latch/decoder, and segment/digit drivers in a single 28-pin DIP package. It supports both static and multiplexed 7-segment LED display operation with digit blanking and test mode functions.
Internal timing is controlled by an external crystal or RC oscillator (100kHz–500kHz), and the device includes automatic carry/borrow propagation between digits, latch enable for data hold, and segment current limiting via internal resistor networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V to 5.5V - compatible with standard TTL/CMOS logic rails and ensures stable LED driver output across industrial voltage tolerances. |
| Max Clock Frequency | 500kHz - enables fast digit updates and supports high-speed counting applications without external synchronization logic. |
| Display Digits | 4-digit BCD - directly drives four 7-segment LED digits with internal multiplexing control, eliminating need for external digit drivers. |
| Segment Drive Type | Common-anode - sources current to LED anodes; requires external cathode sinking (e.g., NPN transistors or low-side drivers) for full brightness control. |
| Operating Temperature | –40°C to +85°C - rated for industrial environments including factory automation panels and embedded metering systems. |
| Package | 28-pin PDIP - through-hole mounting suitable for prototyping, legacy board assembly, and service-replacement applications. |
Pinout & Package
ICM7217BIPI is housed in a 28-pin plastic dual in-line package (PDIP) with 0.6-inch body width and standard 0.1-inch pin pitch. Pin numbering follows JEDEC MS-001, with Pin 1 at top-left corner when notch is oriented upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 28) | Positive supply | Primary 5V power input; must be decoupled locally with 0.1µF ceramic capacitor to ground. |
| GND (Pin 14) | Ground reference | System ground return for all internal logic and segment/digit drivers; shared with LED cathode sink paths. |
| CLK (Pin 2) | Count clock input | Accepts TTL/CMOS-compatible square wave; frequency determines digit update rate and counter speed. |
| LE (Pin 3) | Latch enable | Active-high signal that freezes BCD count into decoder latches, enabling stable display during data loading. |
| TEST (Pin 4) | Display test mode | When high, forces all segments ON for visual verification of LED wiring and continuity. |
| BLANK (Pin 5) | Digit blanking control | Active-low signal that disables all digit outputs - used for leading-zero suppression or display dimming. |
| SEG A–G, DP (Pins 6–12) | Segment outputs | Open-collector (with internal 100kΩ pull-ups) common-anode segment drivers; require external current-limiting resistors per segment. |
| DIG 1–4 (Pins 15–18) | Digit select outputs | Active-low common-anode digit drivers; each sinks current for one digit's cathodes in multiplexed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 4-digit BCD counter | Eliminates need for external decade counters and simplifies timing-critical cascading in digital meter designs. |
| Built-in segment/digit latching | Prevents display flicker during asynchronous count updates by holding decoded values until next LE pulse. |
| On-chip multiplexing control | Generates digit-select timing internally - no external multiplexer IC or microcontroller GPIO required for 4-digit scanning. |
| Test and blanking functions | Enables hardware-level display diagnostics and zero-suppression without firmware intervention or additional logic gates. |
| Internal pull-up resistors | Reduces external component count on segment lines; allows direct connection to common-anode LEDs with only current-limiting resistors needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-digit BCD display controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICL7217CPI | Same architecture and pinout; lower max clock (200kHz) and narrower temp range (0°C to +70°C). | Suitable for commercial-grade instruments but not extended-temperature industrial use. | Select ICL7217CPI only if operating environment stays within 0°C–70°C and clock speed ≤200kHz is acceptable. |
| MM7217AN | Functionally identical; manufactured by National Semiconductor (now TI), same 28-pin DIP package and electrical specs. | No functional or layout differences - historically used interchangeably in legacy designs. | MM7217AN offers second-source availability but shares identical lifecycle status and obsolescence risk with ICM7217BIPI. |
Compared with ICL7217CPI and MM7217AN, the ICM7217BIPI provides the widest operating temperature range and highest clock tolerance, making it the preferred choice for new industrial designs requiring long-term reliability and performance margin.

FAQ
What is the maximum clock frequency supported by the ICM7217BIPI?
The ICM7217BIPI supports a maximum clock frequency of 500kHz. This specification is guaranteed across the full operating temperature range (–40°C to +85°C) and ensures reliable counting and display update performance in high-speed digital meter applications. Exceeding this limit may cause incorrect BCD counting or unstable segment output behavior in the ICM7217BIPI.
Does the ICM7217BIPI support common-cathode LED displays?
No, the ICM7217BIPI is designed exclusively for common-anode 7-segment LED displays. Its segment outputs (A–G, DP) are open-collector with internal 100kΩ pull-up resistors and source current to LED anodes. To drive common-cathode displays, external level-shifting or inversion circuitry would be required - which is not supported by the ICM7217BIPI architecture.
Can the ICM7217BIPI operate from a 3.3V supply?
No, the ICM7217BIPI requires a minimum supply voltage of 4.5V and is specified only for operation between 4.5V and 5.5V. Operation at 3.3V falls outside its guaranteed electrical specifications and will result in improper segment driver output, latch malfunction, or complete failure to count - the ICM7217BIPI is not 3.3V-compatible.
Is the ICM7217BIPI pin-compatible with the ICL7217 series?
Yes, the ICM7217BIPI is pin-compatible and functionally equivalent to the ICL7217CPI and ICL7217MJI in the 28-pin DIP package. All share identical pin assignments, BCD input structure, and control signal definitions, allowing direct substitution in existing layouts - though the ICM7217BIPI extends temperature and frequency ratings beyond the ICL7217 series.
What is the purpose of the TEST pin on the ICM7217BIPI?
The TEST pin (Pin 4) on the ICM7217BIPI is an active-high input that forces all seven segments (A–G) and decimal point (DP) to illuminate simultaneously when asserted. This enables rapid hardware validation of LED connections, segment wiring integrity, and driver functionality without requiring external test patterns - a diagnostic feature unique to the ICM7217BIPI and related family members.
