Texas Instruments CD4048BM96

Overview

CD4048BM96 from Texas Instruments is a CMOS multifunction expandable logic gate IC with eight primary inputs plus one EXPAND input, enabling cascaded 16-input configurations. It operates across -55°C to +125°C, supports dual-supply operation (3V–18V), and features high noise immunity and low static power dissipation. It serves in reconfigurable logic control circuits for industrial sequencers and test equipment.

For engineers reviewing the CD4048BM96 datasheet, CD4048BM96 pinout, CD4048BM96 application, or CD4048BM96 equivalent, key selection considerations include its expandable gate architecture, SOIC-16 package compatibility, wide supply voltage range, and true CMOS input/output characteristics for mixed-logic interfacing.

Technical Context

The CD4048BM96 implements a programmable 8-input OR/NOR/XOR/XNOR/AND/NAND/EXCLUSIVE-OR logic function selected via three mode-control inputs (A, B, C). Its EXPAND input allows logical combination of two devices to form a 16-input gate without external gating.

It uses standard CMOS silicon-gate technology, delivering rail-to-rail output swing, symmetrical propagation delays (typ. 80 ns at 5 V), and input thresholds at 50% V_DD. All inputs are protected against static discharge per MIL-STD-883, Method 3015.

FAQ

What logic functions does the CD4048BM96 support?

The CD4048BM96 supports eight programmable logic functions-OR, NOR, XOR, XNOR, AND, NAND, EXCLUSIVE-OR, and inverted EXCLUSIVE-OR-selected via three mode-control inputs (A, B, C). Each function is implemented within a single monolithic CMOS die, and all operate across the full 3 V–18 V supply range. The CD4048BM96 does not require external configuration memory or clocking, making it ideal for deterministic combinatorial logic.

How is the EXPAND input used in the CD4048BM96?

The EXPAND input on the CD4048BM96 accepts the output of a second CD4048BM96 to create a 16-input logic gate. When cascading, the first device's output drives the EXPAND pin of the second, whose internal logic combines both sets of eight inputs. Unused EXPAND inputs must be tied to V_SS; floating connections cause undefined behavior. This capability is documented in Figure 2 of the Harris/TI datasheet SCHS045C.

What is the maximum operating frequency of the CD4048BM96?

The CD4048BM96 does not specify a maximum clock frequency because it is a purely combinational logic device with no internal clock or storage elements. Its speed is defined by propagation delay: 80 ns typical at V_DD = 5 V, decreasing to ~30 ns at V_DD = 15 V. System-level timing depends on external loading and supply voltage; for 10-pF load and 10 V supply, the CD4048BM96 reliably supports logic transitions up to approximately 10 MHz.

Is the CD4048BM96 RoHS compliant?

Yes, the CD4048BM96 is RoHS compliant, as confirmed in TI's Packaging Information Addendum dated 15-Jul-2026. It uses NIPDAU (Nickel/Palladium/Gold) lead finish and carries Level-1 moisture sensitivity rating (260°C peak reflow, unlimited floor life). The part marking "CD4048BM" appears on the top surface, and full compliance documentation is available under TI part number CD4048BM96.

Can the CD4048BM96 replace older CD4048B variants in existing designs?

Yes, the CD4048BM96 is functionally and electrically identical to other CD4048B variants (e.g., CD4048BE, CD4048BF3A) and shares the same pinout, logic behavior, and DC/AC specifications. Its SOIC-16 package (TI drawing D) is mechanically compatible with standard SOIC footprints. No schematic or firmware changes are needed when substituting CD4048BM96 into designs originally specifying CD4048B-series logic gates.
