Product details
Overview
CD4502BM96 from Texas Instruments is a dual 4-bit bidirectional buffer/line driver in SOIC-16 package, featuring CMOS logic compatibility, ±10 mA output drive capability at VDD = 15 V, and operation across -55°C to +125°C. It enables data direction control via separate enable and phase-select inputs, supporting bus isolation and level translation in industrial control backplanes.
For engineers reviewing the CD4502BM96 datasheet, CD4502BM96 pinout, CD4502BM96 application, or CD4502BM96 equivalent, key selection criteria include its true bidirectional data flow control, high-voltage CMOS tolerance (up to 20 V), independent output enable per port, and compatibility with TTL input thresholds while driving CMOS loads.
Technical Context
The CD4502BM96 implements two independent 4-bit bidirectional buffers, each with dedicated phase (PH) and enable (EN) controls. Its internal architecture uses complementary MOS transistors to support both sourcing and sinking current on each I/O line without external direction lines.
It operates over a wide supply range (3 V to 20 V), exhibits low quiescent current (< 1 µA at 25°C), and maintains rail-to-rail output swing. Input thresholds are TTL-compatible (VIL ≤ 0.8 V, VIH ≥ 2.0 V), enabling direct interfacing with legacy logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CMOS - ensures low power consumption and high noise immunity in mixed-signal systems |
| Supply Voltage Range | 3 V to 20 V - supports direct integration with legacy 5 V, 12 V, and 15 V industrial power rails |
| Output Drive Current | ±10 mA at VDD = 15 V - sufficient to drive multiple CMOS loads or small LEDs without buffering |
| Operating Temperature | -55°C to +125°C - qualified for extended-range military and aerospace applications |
| Propagation Delay | 120 ns max at VDD = 15 V - suitable for sub-MHz synchronous bus control and status monitoring |
| Input Compatibility | TTL-level inputs - allows direct connection to 74LS/74ALS outputs without level-shifting circuitry |
Pinout & Package
CD4502BM96 is housed in a 16-pin SOIC (D) package measuring 10.4 mm × 5.4 mm × 2.0 mm max height, with 1.27 mm pitch leads and RoHS-compliant NiPdAu lead finish. It conforms to JEDEC MS-012 and TI package drawing D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Port A I/O | Bidirectional data lines for first 4-bit channel; direction controlled by PH1 and EN1 |
| 5 | EN1 | Active-high enable for Port A - disables all A-side outputs when low |
| 6 | PH1 | Phase select for Port A - determines data flow direction (A→B or B→A) |
| 7 | VSS | Ground reference for logic and output stages |
| 8, 9, 10, 11 | Port B I/O | Bidirectional data lines for second 4-bit channel; direction controlled by PH2 and EN2 |
| 12 | EN2 | Active-high enable for Port B - independent control of B-side output state |
| 13 | PH2 | Phase select for Port B - sets directionality of B-port data transfer |
| 14 | VDD | Positive supply rail - powers both logic core and output drivers |
| 15, 16 | NC | No-connect pins - internally unused; must remain unconnected per TI design guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4-bit bidirectional buffers | Enables isolated data path management between two subsystems without shared control logic |
| Separate phase and enable per port | Allows asymmetric bus arbitration - e.g., Port A reads while Port B writes simultaneously |
| Wide VDD range (3 V–20 V) | Eliminates need for voltage translators when interfacing 3.3 V microcontrollers to 12 V sensor buses |
| TTL-compatible inputs | Reduces BOM count by removing input-level shifters in mixed-logic designs |
| High-impedance outputs when disabled | Prevents bus contention during hot-swap or partial system reset sequences |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4502BNSR | Same die, SOP-16 package (NS); 2.0 mm height, 1.27 mm pitch, 2000 pcs/reel | Preferred for space-constrained layouts where SOIC footprint is too wide; identical timing and drive specs | Select CD4502BNSR when board real estate requires narrower body width (5.2 mm vs. 5.4 mm) and tape-and-reel volume matches production needs. |
| CD4502BPW | Same die, TSSOP-16 package (PW); 1.2 mm height, 0.65 mm pitch, 90 pcs/tube | Suitable for high-density routing but requires finer-pitch assembly; same electrical performance | Choose CD4502BPW only if SMT line supports 0.65 mm pitch and thermal profile aligns with Level-1 MSL rating. |
Compared with CD4502BNSR and CD4502BPW, the CD4502BM96 offers optimal balance of manufacturability (SOIC-16), volume packaging (2500 pcs/reel), and compatibility with standard 0.050" pitch pick-and-place tooling - making it the default choice for industrial OEM production runs.

FAQ
What is the maximum supply voltage rating for CD4502BM96?
The CD4502BM96 is rated for operation up to 20 V DC on VDD, with guaranteed functionality across the full 3 V to 20 V range. This allows direct use in 12 V and 15 V industrial systems without regulation. Absolute maximum rating is 20 V; exceeding this may cause permanent damage to the CD4502BM96.
Does CD4502BM96 support true bidirectional data flow on each port?
Yes, the CD4502BM96 supports true bidirectional data flow per port via dedicated PH (phase) and EN (enable) inputs. When EN is high, PH selects direction: high enables A→B transfer, low enables B→A transfer. Both ports operate independently, allowing simultaneous asymmetric data movement in the CD4502BM96.
Is CD4502BM96 pin-compatible with other CD4502B variants like CD4502BE or CD4502BF3A?
No - while functionally identical, CD4502BM96 (SOIC-16) is not pin-compatible with CD4502BE (PDIP-16) or CD4502BF3A (CDIP-16) due to differing package footprints and lead forms. Mechanical layout changes are required when substituting packages; the CD4502BM96 requires SOIC-16 land pattern per TI drawing D.
What is the meaning of "M96" in CD4502BM96?
The "M96" suffix in CD4502BM96 indicates the device is packaged in a SOIC-16 (package code D) with tape-and-reel delivery (96 = TI's internal reel code), RoHS-compliant NiPdAu finish, and Level-1 moisture sensitivity rating. It does not denote a functional variant - the CD4502BM96 shares identical logic and electrical behavior with all CD4502B types.
Can CD4502BM96 drive LED indicators directly?
Yes - the CD4502BM96 can sink or source up to ±10 mA per output at VDD = 15 V, sufficient to drive standard 2 mA LEDs with appropriate series resistors. For example, with VDD = 12 V and red LED (VF ≈ 1.8 V), a 1 kΩ resistor yields ~10.2 mA - within safe limits for the CD4502BM96.
