CD4054BF 4-Segment CMOS LCD Driver | Harris 16-CDIP
MPN: CD4054BF ✗ Cuối đờiCD4054BF Tóm tắt
A four-segment CMOS LCD driver is a specialized logic IC that accepts encoded display information and generates the segment-drive outputs required by multiplexed liquid-crystal displays. Within the display-driver hierarchy, it sits between general-purpose CMOS logic and application-specific LCD timing and segment-control circuitry. Its four-segment organization makes it useful for compact numeric, alphanumeric, or segmented indicators where a controller does not directly drive every display electrode.
The verified product data specifically identifies the CD4054BF as a Harris Corporation part and describes a 4-segment LCD-driver configuration in a 16-CDIP package. The B suffix and ceramic package terminology indicate a packaged CD4000-series implementation, while the provided distributor listing classifies it under integrated circuits and display drivers. Detailed electrical timing, supply-voltage, output-drive, and temperature limits require the manufacturer datasheet before design release.
CD4054BF applications include four-segment multiplexed LCD displays, compact numeric indicators, control-panel displays, embedded instrument panels, and low-power handheld equipment. The LCD-driver role is important because it reduces the amount of display-segment routing and control logic required around a system controller. Its CMOS implementation places it in the broader low-power semiconductor and integrated-circuit ecosystem.
The principal design consideration is package and pinout validation. The CD4054BF uses a 16-CDIP package, so a replacement must use the same 16-pin footprint, confirm pin-to-pin signal compatibility, and verify the required supply voltage and display timing. Cross-reference search results identify CD4054BF variants and comparison pages, but they do not establish five verified drop-in replacements with complete package-level engineering data.
This page consolidates verified distributor classification, source links, package information, and practical design guidance. Unavailable electrical values are explicitly marked for follow-up rather than inferred, allowing engineers to move from discovery to datasheet confirmation without treating guesses as specifications.

Ứng dụng tiêu biểu
CD4054BF phù hợp cho 6 Áp dụngs: Compact Numeric LCD Displays, Control-Panel Segment Indicators, Embedded Measurement Instruments, Handheld Device Status Displays, Industrial Status Annunciators, Legacy LCD Instrument Panels.
Compact Numeric LCD Displays
The CD4054BF is suitable for a compact numeric LCD indicator requiring a 4-segment display-driver function. In a multiplexed panel, the device can organize the display-control information so the system controller does not need to reproduce every segment-drive sequence directly. The verified distributor classification supports the LCD-driver use case, but the engineer must confirm the exact segment count, common-plane arrangement, timing, and voltage levels against the target display and manufacturer datasheet.
Được đề xuất
Control-Panel Segment Indicators
Use the CD4054BF in a control panel where a small group of LCD segments indicates operating state, set points, or status. Its 4-segment CMOS LCD-driver classification makes it a fit for legacy instrument panels that use a through-hole display-driver architecture. Because the verified data does not state the output drive or timing, validate the LCD load and pin functions first; do not substitute it solely because another display driver is labeled functionally similar.
Được đề xuất
Embedded Measurement Instruments
The CD4054BF can support segmented readouts in embedded measurement equipment where a low-size CMOS display driver is useful for a four-segment LCD. Its through-hole 16-CDIP package is convenient for repairable industrial and laboratory instruments, although it requires board space and plated-through holes. Confirm the panel's bias voltage, multiplex timing, and logic levels in the datasheet before connecting it to a precision measurement front end.
Được đề xuất
Handheld Device Status Displays
CD4054BF can be considered for legacy handheld products that use a four-segment LCD status indicator and retain a through-hole controller layout. CMOS operation places it within the low-power logic ecosystem, while the 4-segment organization can simplify display-drive decoding for a simple status panel. The supplied data does not include battery-current specifications or operating voltage, so battery life and supply-headroom calculations require the manufacturer datasheet before design approval.
Được đề xuất
Industrial Status Annunciators
For an industrial status annunciator, the CD4054BF can decode signals intended for a four-segment LCD indicator while keeping the display interface electrically isolated from the main controller logic. The 16-CDIP format suits repairable industrial equipment and legacy control cards. Engineers should verify common-mode voltage, segment drive level, refresh timing, and available panel drive current, because none of these detailed values are present in the verified distributor snippets.
Được đề xuất
Legacy LCD Instrument Panels
The CD4054BF is a candidate for retrofitting legacy LCD instrument panels that use a 4-segment display-driver arrangement and a 16-pin through-hole footprint. It can reduce the need for a controller to generate dedicated segment outputs, provided the original timing and electrical interface are reproduced. Before substitution, compare the complete pinout, supply voltage, display bias, and temperature grade with the original manufacturer datasheet.

Ghi chú thiết kế
Treat the 16-CDIP footprint and LCD signal routing as the primary replacement constraint. Before layout release, compare the complete pin assignment, segment outputs, common-plane connection, supply pins, and bypass requirements against the original design. The supplied distributor data confirms a 16-CDIP package but does not provide a complete pinout, so do not derive connections from package position alone.
Keep LCD drive traces short and isolate them from switching nodes and sensitive analog inputs. Use the manufacturer’s recommended grounding and supply bypassing once those values are obtained from the datasheet. Confirm the display’s common-plane bias and segment voltage limits in the actual panel specification; a valid driver pin assignment does not guarantee safe LCD electrode drive.
Do not select CD4054BF solely because a distributor labels another part as an equivalent. First verify identical 16-CDIP footprint, pinout, supply range, display timing, output drive, and temperature grade. The comparison search identifies CD4054BE, CD4054BPW, and CD4054BPWRG4 as candidates, but the supplied snippets do not establish a complete five-part drop-in set or all electrical differences.
