Product details

Overview

CD4028BM96 from Texas Instruments is a BCD-to-decimal decoder/driver IC in a 16-pin SOIC package, operating across -55°C to +125°C, with supply voltage range 3 V to 18 V, and typical propagation delay of 100 ns at 5 V. It converts 4-bit binary-coded decimal inputs into ten active-high decimal outputs for driving indicators or logic control in digital instrumentation.

For engineers reviewing the CD4028BM96 datasheet, CD4028BM96 pinout, CD4028BM96 application, or CD4028BM96 equivalent, key selection considerations include its CMOS-compatible input thresholds, TTL-level output drive capability, wide temperature range, and compatibility with legacy 4000-series logic families in industrial control and test equipment design.

Technical Context

The CD4028BM96 implements combinational logic decoding using standard CMOS gate arrays to map four BCD input bits (A–D) to ten mutually exclusive active-high outputs (0–9). Its internal structure includes NAND-based decoding gates with buffered outputs capable of sourcing/sinking ±4.2 mA at 5 V.

No latching, clocking, or enable control is integrated - operation is purely level-sensitive and asynchronous. Input hysteresis is not specified; inputs are compatible with both CMOS and TTL logic levels when V_DD ≥ 5 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Function	BCD-to-decimal decoder with active-high outputs
Supply Voltage Range	3 V to 18 V - supports battery-powered and industrial rail systems
Operating Temperature	-55°C to +125°C - qualified for extended industrial and automotive under-hood use
Propagation Delay	100 ns max at V_DD = 5 V - enables reliable timing in synchronous 100 kHz+ counting systems
Output Drive	±4.2 mA at V_DD = 5 V - directly drives LEDs or interfaces to 74HC/74LS inputs without buffers
Input Compatibility	CMOS- and TTL-compatible inputs at V_DD ≥ 5 V - simplifies mixed-logic system integration

Pinout & Package

CD4028BM96 is housed in a 16-pin SOIC (D) package per JEDEC MS-012, 7.5 mm body width, 1.75 mm height, 1.27 mm lead pitch, and gull-wing leads. Pin 1 is located at the top-left corner with notch or beveled edge marking.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 6, 7	BCD Inputs (A–D)	Active-high inputs accepting standard CMOS/TTL logic levels; A = LSB, D = MSB
3–5, 9–11, 13, 14	Decimal Outputs (0–9)	Active-high decoded outputs - only one asserted per valid BCD input; high-impedance when invalid
8	V_SS	Ground reference terminal - must be connected to system common return
16	V_DD	Positive supply terminal - decouples noise with local 0.1 µF ceramic capacitor

Key Features

Feature	Design Value
Wide Supply Range	3 V to 18 V operation enables single-supply designs across battery, 5 V, and 12 V systems
High Noise Immunity	CMOS input structure provides >50% V_DD noise margin - robust in electrically noisy environments
Low Static Current	Typical I_DD = 100 nA at V_DD = 5 V - suitable for low-power portable instrumentation
Unlatched Operation	Combinational logic only - no internal storage; eliminates metastability concerns in real-time decode paths

Equivalent & Alternatives

The following parts are listed as comparable options for similar BCD-to-decimal decoder applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4028BE	Same logic function and pinout; PDIP-16 package with wider body and through-hole mounting	Suitable for prototyping, manual assembly, or legacy through-hole PCBs	Select CD4028BE when board layout requires through-hole components or hand-soldering during development
CD4028BNSR	Same logic and SOIC footprint but uses SOP-16 (NS) package with 1.27 mm pitch and 1.75 mm height	Compatible with higher-density layouts where NS package allows tighter trace routing	Choose CD4028BNSR if existing SOP-16 land patterns or stencil designs are already validated

Compared with CD4028BE and CD4028BNSR, the CD4028BM96 offers identical electrical performance and logic behavior in a standardized SOIC-D package with tape-and-reel delivery optimized for SMT production - making it ideal for volume manufacturing where consistent reflow profile and pick-and-place compatibility are required.

FAQ

What is the maximum supply voltage rating for CD4028BM96?

The CD4028BM96 is rated for operation up to 18 V DC on V_DD, with absolute maximum ratings specifying 20 V. Exceeding 18 V may cause accelerated parametric drift or latch-up in sustained operation. The CD4028BM96 maintains full functionality and timing specifications across its entire 3 V to 18 V range, making it suitable for variable-voltage battery-backed systems.

Does CD4028BM96 have built-in output current limiting?

No, the CD4028BM96 does not include internal output current limiting circuitry. Its outputs are standard CMOS push-pull stages rated for ±4.2 mA at 5 V. External current-limiting resistors are required when driving LEDs directly. The CD4028BM96 output structure relies on inherent MOSFET on-resistance for current control, so load impedance must be selected to stay within safe operating area limits.

Is CD4028BM96 pin-compatible with TTL BCD decoders like the 7442?

No, CD4028BM96 is not pin-compatible with the 7442. While both perform BCD-to-decimal decoding, the 7442 uses active-low outputs and different pin assignments (e.g., 7442 has inverted outputs and distinct enable logic). The CD4028BM96 features active-high outputs and no enable input, requiring PCB redesign or level-shifting circuitry for direct substitution.

What is the MSL rating for CD4028BM96 and how does it affect handling?

The CD4028BM96 carries an MSL Level-1 rating per JEDEC J-STD-020, meaning it has unlimited floor life and may be exposed to ambient conditions indefinitely before reflow. This eliminates bake requirements and simplifies SMT line logistics. The CD4028BM96's Level-1 classification reflects its SOIC-D package construction and moisture barrier properties, supporting standard factory handling without dry-pack or humidity-controlled storage.

Can CD4028BM96 decode invalid BCD codes (10–15)?

No, the CD4028BM96 does not assert any output for invalid BCD inputs (1010 to 1111). All ten outputs remain low during these states, providing inherent error indication. This behavior is defined in the CD4028BM96 truth table and applies across its full voltage and temperature range - no additional external logic is needed to detect illegal codes in safety-critical decode paths.
