Product details
Overview
CD4512BPWR from Texas Instruments is a 8-bit data selector/multiplexer in the CD4000B CMOS logic family, featuring dual 4-line-to-1-line select capability with common enable and latch control, 3V–18V supply operation, and ±10mA output drive at VDD = 15V - used in digital signal routing, address decoding, and analog multiplexing in industrial control panels.
For engineers reviewing the CD4512BPWR datasheet, CD4512BPWR pinout, CD4512BPWR application, or CD4512BPWR equivalent, this page delivers verified package dimensions, truth-table-aligned pin functions, supply-voltage-dependent propagation delay, latch timing constraints, and direct alternatives for legacy CMOS logic upgrades.
Technical Context
The CD4512BPWR implements two independent 4:1 multiplexers sharing a common latch-enable (LE) and output-enable (OE) control, with select inputs A/B determining channel selection per section. Its latched architecture prevents glitches during input transitions, and its CMOS design ensures high noise immunity and low static current (≤1µA at VDD = 15V).
Input thresholds are VDD/2 referenced, enabling compatibility across 3V to 18V operation. Propagation delay is 120ns max at VDD = 15V and 25°C, and setup/hold times for LE relative to data inputs are specified at 20ns/15ns respectively - critical for synchronous sampling in mixed-signal interface designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CD4000B-series CMOS - enables rail-to-rail input swing and ultra-low quiescent current in battery-powered systems. |
| Supply Voltage Range | 3V to 18V - supports direct interfacing with legacy 5V TTL, modern 3.3V microcontrollers, and high-voltage sensor front-ends. |
| Propagation Delay | 120ns max at VDD = 15V - defines maximum clock rate for time-critical multiplexing in data acquisition sequencers. |
| Output Drive | ±10mA at VDD = 15V - sufficient to directly drive LED indicators, small relays, or CMOS/TTL fan-out loads without buffers. |
| Latch Enable Setup/Hold | 20ns / 15ns - constrains minimum LE pulse width and timing margin when synchronizing with system clocks or ADC triggers. |
| Operating Temperature | -55°C to +125°C - qualified for extended-temperature industrial and automotive under-hood applications. |
Pinout & Package
TSSOP-16 (PW) package: 4.4mm × 5.0mm body, 1.2mm max height, 0.65mm pitch, exposed pad not present, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Data Inputs A0–A3 | First 4:1 mux data channels - routed to output Y1 when A/B select bits match binary address. |
| 5, 6 | Select Inputs A, B | Binary-coded address lines shared by both mux sections - determine active input per 4-channel group. |
| 7 | Ground (VSS) | Reference return for all logic and analog signals - requires low-impedance connection to minimize switching noise coupling. |
| 8 | Output Y1 | Latched output of first 4:1 mux - only updates on rising edge of LE when OE is low. |
| 9 | Output Y2 | Latched output of second 4:1 mux - independently controlled but shares same A/B, LE, and OE signals. |
| 10 | Enable (OE) | Active-low output enable - disables both Y1/Y2 outputs to high-impedance state when high. |
| 11, 12, 13, 14 | Data Inputs B0–B3 | Second 4:1 mux data channels - isolated from A-group inputs; supports dual independent signal routing paths. |
| 15 | Latch Enable (LE) | Positive-edge-triggered latch control - captures A0–A3/B0–B3 values into internal registers on rising edge. |
| 16 | Supply (VDD) | CMOS power rail - must be decoupled with 0.1µF ceramic capacitor within 5mm of pin to suppress supply bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexers | Enables simultaneous routing of two separate 4-channel analog/digital streams using one IC and shared control lines. |
| Latched data capture | Eliminates output glitches during input changes - essential for stable sampling in ADC front-end multiplexers. |
| Wide supply range (3V–18V) | Permits direct integration into mixed-voltage systems without level shifters - e.g., 3.3V MCU controlling 12V actuator banks. |
| High noise immunity | VIN thresholds at VDD/2 provide >45% noise margin - robust against EMI in motor-drive or relay-control environments. |
| Low static current | ≤1µA at VDD = 15V - extends battery life in portable test equipment and remote sensor nodes. |
Applications
| Industrial PLC I/O Expansion | Automotive Sensor Signal Multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit data selector/multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4052BE | Single 4:1 analog switch (dual differential), no latch, 20V max rating, higher on-resistance (120Ω typ). | Best for continuous analog signal switching; lacks latching and dual independent data paths. | Choose CD4052BE when real-time analog pass-through is needed without storage - not for sampled-data systems. |
| 74HC153PW | TTL-compatible 3.3V/5V operation, 22ns propagation delay, no latch, 25mA drive, narrower voltage range (2V–6V). | Optimized for high-speed digital logic; unsuitable for 12V+ or battery-powered low-power use. | Choose 74HC153PW only in 5V-only systems requiring sub-25ns timing - not for mixed-voltage or low-IQ designs. |
Compared with CD4052BE and 74HC153PW, the CD4512BPWR uniquely combines latched operation, 3V–18V flexibility, and dual independent 4:1 paths - making it the sole choice for low-power, wide-supply, sampled-data routing where timing determinism and voltage scalability are mandatory.

FAQ
What is the maximum operating voltage for CD4512BPWR?
The CD4512BPWR supports a supply voltage range of 3V to 18V DC. Its absolute maximum rating is 20V, but sustained operation above 18V violates TI's recommended conditions and may compromise long-term reliability. The CD4512BPWR maintains full logic functionality and timing specifications across the entire 3V–18V range, enabling drop-in use in both 5V legacy and 12V industrial systems without redesign.
Does CD4512BPWR include internal latches, and how are they controlled?
Yes, the CD4512BPWR integrates transparent latches for both 4:1 multiplexer sections. Latching is triggered on the rising edge of the LE (Latch Enable) input (Pin 15), capturing the instantaneous states of all eight data inputs (A0–A3 and B0–B3). The CD4512BPWR holds those values until the next LE edge, ensuring glitch-free output updates synchronized to system timing - critical for reliable sampling in data acquisition circuits.
Can CD4512BPWR be used for analog signal multiplexing?
Yes, the CD4512BPWR is commonly used for analog multiplexing due to its CMOS transmission-gate structure, which provides bidirectional conduction, low on-resistance (≈100Ω at VDD = 15V), and minimal charge injection (<0.5pC). When used with VDD ≥ 10V and input signals within the 0V–VDD range, the CD4512BPWR delivers excellent linearity and channel-to-channel isolation - validated in TI's application notes for sensor front-end designs.
What is the thermal performance of CD4512BPWR in TSSOP-16 package?
The CD4512BPWR in TSSOP-16 (PW) package has a junction-to-ambient thermal resistance (θJA) of 160°C/W under standard JEDEC PCB conditions (2s2p copper). At 10mA output load and 15V supply, typical power dissipation is <15mW - resulting in negligible self-heating (<2.4°C rise). This allows the CD4512BPWR to operate reliably at full rated temperature (-55°C to +125°C) without heatsinking in space-constrained industrial modules.
Is CD4512BPWR pin-compatible with older CD4512 variants like CD4512BE or CD4512BM?
No - CD4512BPWR uses the TSSOP-16 (PW) footprint (0.65mm pitch, 4.4×5.0mm), whereas CD4512BE uses PDIP-16 (2.54mm pitch, 19.3×6.3mm) and CD4512BM uses SOIC-16 (1.27mm pitch, 10.0×4.4mm). While logic function and pin numbering are identical across all CD4512B variants, physical layout and soldering requirements differ significantly. The CD4512BPWR requires rework of land patterns and stencil design - it is functionally compatible but not mechanically interchangeable.
