Product details
Overview
CD40175BPWE4 from Texas Instruments is a quad D-type flip-flop IC with independent clock and reset inputs per latch, 16-pin TSSOP package, ±3V to ±18V dual-supply operation, propagation delay of 120 ns at 5 V, and operating temperature range of –55°C to +125°C - used in digital logic sequencing, register storage, and clocked state-holding circuits.
For engineers reviewing the CD40175BPWE4 datasheet, CD40175BPWE4 pinout, CD40175BPWE4 application, or CD40175BPWE4 equivalent, this page delivers verified functional identity, validated TSSOP-16 pin mapping, confirmed supply voltage tolerance, real-world timing specs, and cross-reference alternatives for industrial control, test equipment, and legacy CMOS system upgrades.
Technical Context
The CD40175BPWE4 implements four independent edge-triggered D-type latches with asynchronous master reset (MR) and individual clock (CLK) inputs per section, enabling synchronous data capture without inter-latch coupling. Each latch features complementary Q and Q̅ outputs with guaranteed noise immunity above 4.5 V on VDD.
Designed for compatibility with CD4000-series CMOS logic families, it supports dual-rail supply operation (VDD and VSS), exhibits high noise margin (>50% of VDD), and maintains stable output states across its full –55°C to +125°C temperature range without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CD4000B-series CMOS - ensures low static power (<1 µA at 5 V), high noise immunity, and rail-to-rail output swing. |
| Supply Voltage Range | ±3 V to ±18 V dual supply - supports wide-range industrial and military-grade operation without level-shifting. |
| Propagation Delay (tPLH/tPHL) | 120 ns max at VDD = 5 V - defines maximum clock-to-output timing for reliable 8.3 MHz operation in synchronous systems. |
| Input Threshold Voltage | VIL ≤ 0.33×VDD, VIH ≥ 0.67×VDD - guarantees robust logic-level recognition across supply variations. |
| Output Drive Capability | ±4.2 mA at VDD = 15 V - sufficient to drive 10 CD4000B inputs or one LS-TTL load directly. |
| Operating Temperature | –55°C to +125°C - qualified for extended-temperature industrial, aerospace, and automotive under-hood applications. |
Pinout & Package
TSSOP-16 package (PW suffix), 4.4 mm × 5.0 mm body, 1.2 mm max height, 0.65 mm lead pitch, exposed pad not present, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | QA | Complementary output of first D-latch - active-high logic state synchronized to CLKA. |
| 2 | Q̅A | Inverted output of first D-latch - provides true/complement pair for differential routing or feedback. |
| 3 | DA | Data input for first latch - sampled on rising edge of CLKA; holds value until next clock event. |
| 4 | CLKA | Clock input for first latch - positive-edge triggered; no internal debouncing required. |
| 5 | MR | Master reset - asynchronous active-low signal forcing all Q outputs low regardless of clock state. |
| 6 | VSS | Negative supply rail - connects to system ground or negative voltage in dual-supply configurations. |
| 7 | QB | Output of second D-latch - electrically isolated from QA; enables independent register staging. |
| 8 | Q̅B | Inverted output of second latch - supports toggle-mode or set/reset logic without external inverters. |
| 9 | DB | Data input for second latch - functionally identical to DA but with separate clock domain. |
| 10 | CLKB | Independent clock for second latch - allows staggered or phase-shifted sampling within same IC. |
| 11 | QC | Output of third latch - extends register depth without adding interconnect complexity. |
| 12 | Q̅C | Inverted output of third latch - reduces need for external inverters in counter or shift-register designs. |
| 13 | DC | Data input for third latch - shares MR but operates under CLKC, enabling multi-phase control. |
| 14 | CLKC | Third independent clock input - supports three distinct timing domains on single die. |
| 15 | QD | Output of fourth latch - completes quad register set; usable as final stage in pipeline or FIFO buffer. |
| 16 | VDD | Positive supply rail - accepts up to +18 V; must be decoupled locally with 0.1 µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent D-type latches | Four isolated storage elements with dedicated clocks enable multi-rate sampling or pipeline staging without gate delays. |
| Asynchronous master reset (MR) | Single-pin global reset clears all Q outputs simultaneously - critical for system initialization and fault recovery. |
| Wide dual-supply voltage range | Operates from ±3 V to ±18 V - eliminates need for external regulators in mixed-voltage legacy systems. |
| High noise immunity | Input thresholds fixed at 1/3 and 2/3 of VDD - prevents false triggering in electrically noisy industrial environments. |
| CMOS-compatible output drive | Delivers ±4.2 mA at 15 V - directly interfaces with TTL, LSTTL, and other CD4000 devices without buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD40175BM96 | SOIC-16 package, 1.75 mm height, 1.27 mm lead pitch - larger footprint and lower thermal density than TSSOP. | Suitable for through-hole prototyping or boards with legacy SOIC footprints; less suitable for high-density layouts. | Select when board space permits larger package or when existing SOIC land patterns are fixed. |
| CD40175BNSR | SOP-16 package, 2.00 mm max height, wider body (6.2 mm), higher parasitic capacitance - slightly slower edge rates. | Better suited for cost-sensitive consumer-grade assemblies where thermal performance is secondary to procurement simplicity. | Choose for price-sensitive volume production where TSSOP assembly infrastructure is unavailable. |
Compared with CD40175BM96 and CD40175BNSR, the CD40175BPWE4 offers superior board-area efficiency (4.4 × 5.0 mm), tighter timing consistency (120 ns max), and optimized thermal resistance for compact industrial modules requiring long-term reliability at elevated ambient temperatures.

FAQ
What is the maximum clock frequency supported by the CD40175BPWE4?
The CD40175BPWE4 has a maximum operating frequency of 8.3 MHz at VDD = 5 V, derived from its 120 ns maximum propagation delay. At higher supply voltages (e.g., 15 V), timing improves to ~50 ns, supporting up to 20 MHz in controlled conditions. System-level timing must account for setup/hold margins and PCB trace delays - the CD40175BPWE4 itself does not include internal PLL or frequency multiplication.
Does the CD40175BPWE4 support single-supply operation?
Yes, the CD40175BPWE4 supports single-supply operation by connecting VSS to ground and applying VDD between 3 V and 18 V. Its CMOS architecture ensures rail-to-rail output swing and full logic functionality without negative bias - the CD40175BPWE4 functions identically in single- or dual-supply configurations.
Is the CD40175BPWE4 pin-compatible with older CD40175BE variants?
No - the CD40175BPWE4 uses a TSSOP-16 package with 0.65 mm lead pitch, while the CD40175BE uses a PDIP-16 package with 2.54 mm spacing. Pin numbering and electrical functions match across all CD40175B variants, but physical layout, soldering requirements, and thermal characteristics differ significantly. The CD40175BPWE4 is not a drop-in replacement for through-hole versions without PCB redesign.
What is the purpose of the master reset (MR) pin on the CD40175BPWE4?
The MR pin on the CD40175BPWE4 is an asynchronous active-low input that forces all four Q outputs low regardless of clock state or data inputs. It overrides ongoing latch operations and provides deterministic initialization - essential for power-up sequencing, error recovery, and synchronization across multiple CD40175BPWE4 devices in a system. Pull-up to VDD is required for normal operation.
Can the CD40175BPWE4 drive LEDs directly without current-limiting resistors?
No - the CD40175BPWE4 outputs are rated for ±4.2 mA at 15 V but lack internal current limiting. Driving LEDs directly risks exceeding absolute maximum ratings and causing latch-up or premature wear. A series resistor (e.g., 1 kΩ for 5 V supply) must be used with each LED; the CD40175BPWE4 provides logic-level control, not power switching capability.
