Product details
Overview
HEF4952BT,112 from NXP Semiconductors is a dual 3-channel analog multiplexer/demultiplexer with supplementary switches and common select logic, operating across −40 °C to +85 °C. It features Schmitt-trigger control inputs (S1–S3), 15 V max supply rating, 45 Ω typical ON resistance at 10 V, and symmetrical bidirectional analog switching for industrial signal routing applications.
For engineers reviewing the HEF4952BT,112 datasheet, HEF4952BT,112 pinout, HEF4952BT,112 application, or HEF4952BT,112 equivalent, this device supports precise analog/digital signal gating in mixed-signal systems where channel isolation, low leakage (<200 nA OFF-state), and rail-to-rail analog handling with VEE support are required.
Technical Context
The HEF4952BT,112 integrates two independent 3-channel analog MUX/DEMUX blocks sharing three digital select lines (S1–S3) and featuring configurable Y3 terminals that route to either VSS or Y2. Each block includes a common Z terminal (1Z/2Z) and four Y ports (Y0–Y3), enabling flexible signal path selection via a 3-bit decoder with Schmitt-trigger inputs for noise immunity.
It operates with dual-supply capability: VDD (5–15 V) and VEE (−15 to 0 V), allowing true bipolar analog signal handling. Clamp diodes on all digital inputs permit current-limited interfacing above VDD, and static operation ensures zero static power draw in steady state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | VDD = 5–15 V; VEE = −15 to 0 V - enables bipolar analog signal routing and rail-to-rail input/output swing |
| ON resistance (typ) | 45 Ω at VDD = 10 V, VI = 0 V - ensures minimal insertion loss and signal distortion in precision analog paths |
| OFF-state leakage | <200 nA per channel at 15 V - maintains high channel-to-channel isolation in high-impedance sensor or DAC interfaces |
| Propagation delay | 2–6 ns (tPHL/tPLH) at 10–15 V - supports fast digital control of analog signal paths without timing bottlenecks |
| Input hysteresis | 0.10–0.16 V (VT+ − VT−) - rejects noise on S1–S3 control lines in electrically noisy industrial environments |
| Operating temperature | −40 °C to +85 °C - certified for continuous use in industrial control cabinets and outdoor instrumentation |
| Package | SO16 (SOT109-1), 3.9 mm body width - surface-mount compatible with standard 0.050″ pitch PCB assembly |
Pinout & Package
HEF4952BT,112 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads and 3.9 mm body width, optimized for automated placement and reflow soldering in industrial-grade assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 6, 11, 12, 14, 16 | 1Y0/1Y1/1Y2/1Y3/2Y0/2Y1/2Y2/2Y3 | Independent analog I/O ports - each functions bidirectionally; Y3 configurable to Y2 or VSS |
| 2, 15 | 2Z / 1Z | Common analog I/O terminals - shared by Y0–Y2 of respective channel; carry routed signal |
| 4 | VEE | Negative supply rail - sets lower analog voltage limit; supports bipolar signal handling |
| 7, 9, 10 | S1 / S2 / S3 | Digital select inputs with Schmitt-trigger action - ensure clean switching despite slow or noisy control edges |
| 8 | VSS | Digital ground reference - decouples digital logic from analog signal paths |
| 13 | VDD | Positive digital supply - powers internal logic and level shifters; up to 15 V rated |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-channel MUX/DEMUX | Two fully isolated analog switch arrays share only S1–S3 controls - simplifies routing while preserving channel independence |
| Configurable Y3 terminal | Each channel's Y3 connects to Y2 or VSS under control - enables dynamic signal shorting or grounding for test modes or safety shutdowns |
| Clamp diode protected inputs | S1–S3 inputs include integrated clamp diodes - allows external current-limiting resistors for overvoltage-tolerant control interface |
| Symmetrical output characteristics | Matched ON resistance and capacitance across all Y/Z paths - ensures consistent signal integrity regardless of direction or channel |
| JEDEC JESD13-B compliance | Fully standardized pinout and electrical behavior - guarantees interoperability with legacy HEF4000-series designs and tooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4052BE | Single-supply only (VDD = 3–15 V); no VEE pin; higher typical RON (120 Ω at 10 V); no Y3 configuration | Lacks bipolar signal support and Y3 flexibility; suitable only for unipolar industrial signal routing | Choose CD4052BE only when VEE is unavailable and bipolar operation is unnecessary. |
| 74HC4052PW | CMOS version; VDD = 2–10 V only; no VEE; 50 Ω RON (typ); no clamp diodes on inputs | Not rated for industrial temperature range; requires clean 5 V logic interface; unsuitable for >10 V analog rails | Select 74HC4052PW only for commercial-grade 5 V systems where cost and speed outweigh ruggedness requirements. |
Compared with CD4052BE and 74HC4052PW, the HEF4952BT,112 uniquely supports true bipolar analog operation via VEE, offers configurable Y3 routing, and delivers lower ON resistance with industrial-temperature-rated Schmitt-trigger inputs - making it the only option among the three qualified for harsh-environment mixed-signal routing with signal integrity assurance.

FAQ
What is the maximum allowable voltage difference between VDD and VEE for HEF4952BT,112?
The HEF4952BT,112 supports a maximum VDD–VEE differential of 15 V, as specified in the recommended operating conditions. For example, VDD = +15 V and VEE = 0 V, or VDD = +10 V and VEE = −5 V, are valid configurations. Exceeding 15 V risks permanent damage per absolute maximum ratings in Table 4.
Can HEF4952BT,112 operate with VEE tied to VSS (i.e., single-supply mode)?
Yes, HEF4952BT,112 can operate with VEE = VSS = 0 V, functioning as a unipolar analog switch. In this configuration, all analog signals must remain within 0 V to VDD. The device retains full functionality including Y3 routing to VSS and Schmitt-trigger inputs, but loses bipolar signal capability.
What is the purpose of the Y3 terminal in HEF4952BT,112, and how is it controlled?
The Y3 terminal in HEF4952BT,112 is configurable via the function table: when S3 = L, Y3 connects to VSS; when S3 = H and S2 = H, Y3 connects to Y2. This allows dynamic grounding or signal shorting - useful for test-mode calibration, fault isolation, or safety discharge paths without external components.
Does HEF4952BT,112 require external pull-up or pull-down resistors on S1–S3 inputs?
No, HEF4952BT,112 does not require external pull-up or pull-down resistors on S1–S3 because its inputs feature built-in Schmitt-trigger action with defined VT+ and VT− thresholds. However, current-limiting resistors are recommended if control signals exceed VDD or fall below VSS, leveraging the integrated clamp diodes per Section 1.
How does the ON resistance mismatch (ΔRON) affect precision analog multiplexing in HEF4952BT,112?
The HEF4952BT,112 specifies ΔRON ≤ 10 Ω between channels at VDD = 10 V and VI = 2.5 V. This tight matching ensures consistent gain and offset across multiplexed channels - critical in applications like multi-sensor data acquisition where channel-to-channel ratio accuracy must be preserved without per-channel calibration.
