Product details
Overview
CD4076BM96 from Texas Instruments is a CMOS 4-bit D-type latch with non-inverting outputs, operating over 3V–18V supply range, featuring high noise immunity (≥50% VDD), low static current (≤1 µA at 10 V), and TTL/CMOS-compatible inputs. It is used in digital data storage, bus interfacing, and address latching in industrial control logic.
For engineers reviewing the CD4076BM96 datasheet, CD4076BM96 pinout, CD4076BM96 application, or CD4076BM96 equivalent, key selection factors include its 16-pin SOIC-D package, 100 ns max propagation delay at 5 V, input threshold symmetry, latch enable timing constraints, and compatibility with legacy 4000B-series logic families.
Technical Context
The CD4076BM96 implements four independent edge-triggered D-type latches with common enable (LE) control. Each latch samples the D input on the rising edge of LE and holds the value until the next LE transition.
It uses standard CMOS silicon-gate technology, ensuring rail-to-rail output swing, symmetrical input thresholds (VIL = 0.33 VDD, VIH = 0.67 VDD), and operation across –55°C to +125°C for selected variants - though CD4076BM96 is rated for –40°C to +85°C per TI's SOIC packaging specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CD4000B-series CMOS - ensures wide VDD range and high noise margin |
| Supply Voltage Range | 3 V to 18 V - supports mixed-voltage system interfacing without level shifters |
| Propagation Delay (tPD) | 100 ns max at VDD = 5 V - defines maximum clock-to-output timing for synchronous latch updates |
| Input Threshold Ratio | VIL ≤ 0.33 VDD, VIH ≥ 0.67 VDD - guarantees robust switching with slow or noisy input edges |
| Quiescent Current (IDD) | ≤1 µA at VDD = 10 V - enables ultra-low-power hold states in battery-backed systems |
| Output Drive Capability | ±4.2 mA at VDD = 15 V - sufficient to drive 10 LS-TTL loads or parallel CMOS inputs |
Pinout & Package
CD4076BM96 is housed in a 16-lead SOIC (Small-Outline Integrated Circuit) package per drawing D, with 1.27 mm lead pitch, gull-wing leads, and JEDEC MS-012 compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Data Inputs (D1–D4) | Asynchronous data inputs to individual latches; high-impedance CMOS inputs |
| 2, 4, 6, 8 | Outputs (Q1–Q4) | Non-inverting latched outputs; full rail-swing CMOS drive |
| 9 | Ground (VSS) | Reference return path for all internal logic and I/O |
| 10 | Latch Enable (LE) | Active-High control signal enabling simultaneous capture of all four D inputs |
| 11–14 | Unused (NC) | No internal connection - must be left unconnected or tied to VSS/VDD per layout guidelines |
| 15 | Power Supply (VDD) | Positive supply rail; decoupling capacitor required within 1 cm |
| 16 | Not Used (NC) | No internal connection - no external tie required |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3 V to 18 V operation enables direct use in legacy 5 V, modern 3.3 V, and high-voltage industrial rails |
| High Noise Immunity | Input noise margin ≥50% VDD prevents false triggering in electrically noisy PLC or motor-control environments |
| Low Power Consumption | Sub-microamp quiescent current allows deployment in always-on monitoring circuits without thermal derating |
| TTL/CMOS Compatibility | Input thresholds match both TTL logic levels and CMOS swing - simplifies mixed-family board design |
Applications
| Industrial PLC I/O Expansion | Digital Panel Meter Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4076BE | Same logic function and AC/DC specs, but in 16-pin PDIP (N package) with through-hole mounting | Suitable for prototyping, breadboarding, or legacy through-hole PCBs where SOIC footprint is unavailable | Select CD4076BE when manual assembly, socketing, or thermal mass requirements favor DIP over SOIC |
| 74HC173PW | 3-state outputs, higher speed (20 ns @ 4.5 V), but requires dual-supply (VCC/GND only) and lacks wide-VDD range | Better for high-speed bus driving with tristate control; not suitable for 12–15 V industrial rails | Choose 74HC173PW only in 3.3 V/5 V systems needing output disable capability and faster timing |
Compared with CD4076BE and 74HC173PW, CD4076BM96 uniquely balances wide supply flexibility, low static power, and SOIC surface-mount compatibility - making it optimal for cost-sensitive, space-constrained industrial controllers requiring robust 3–18 V operation.

FAQ
What is the maximum operating temperature for CD4076BM96?
The CD4076BM96 is specified for operation from –40°C to +85°C ambient temperature, consistent with its SOIC-D packaging and commercial-grade qualification. This range supports deployment in enclosed industrial cabinets and non-hermetic instrumentation enclosures without forced cooling. The underlying CD4000B process allows extended temperature variants (e.g., CD4076BF3A) up to +125°C, but CD4076BM96 itself is not rated beyond +85°C.
Does CD4076BM96 support 3.3 V logic systems?
Yes, CD4076BM96 operates reliably down to 3 V supply, with verified input thresholds (VIL ≤ 1.0 V, VIH ≥ 2.0 V at VDD = 3.3 V) and output swing exceeding 3.0 V. Its CMOS inputs accept 3.3 V TTL-level signals directly, and outputs drive standard 3.3 V CMOS loads without level translation. Full AC performance (e.g., tPD) is characterized at 5 V and 10 V, but functional operation is guaranteed across the entire 3–18 V range.
Are pins 11–14 and 16 of CD4076BM96 internally connected?
No, pins 11–14 and 16 of CD4076BM96 are No Connect (NC) terminals with no internal bond wires or circuit connections. TI's datasheet explicitly lists them as unused. They must remain unconnected in PCB layout; tying them to VDD or VSS is unnecessary and may risk unintended coupling. This NC configuration is consistent across all CD4076B variants in SOIC, TSSOP, and PDIP packages.
How does the latch enable (LE) timing work on CD4076BM96?
CD4076BM96 uses positive-edge-triggered latch enable: the Q outputs update to match D inputs only on the rising edge of LE. While LE is low, outputs retain their last latched state regardless of D input changes. Setup time (tsu) is 30 ns min before LE rise, and hold time (th) is 20 ns min after LE rise - values measured at VDD = 5 V. These timing parameters ensure reliable capture in synchronous digital systems using standard clock buffers.
Is CD4076BM96 RoHS-compliant and lead-free?
Yes, CD4076BM96 is RoHS-compliant and lead-free, classified under TI's "Green (RoHS & no Sb/Br)" eco-plan. Its SOIC-D package uses Cu-Ni-Pd-Au (CU NIPDAU) lead finish and meets JEDEC Level-1 moisture sensitivity (unlimited floor life at <30°C/60% RH). TI documentation confirms Pb-free conversion for this part number, with no exemptions applied - making it suitable for environmentally regulated industrial and consumer products.
