Product details

Overview

CD4504BMG4 from Texas Instruments is a CMOS hex non-inverting buffer/driver with TTL-to-CMOS level translation capability, operating across ±5 V to ±15 V dual-supply or 5 V to 20 V single-supply configurations, delivering 8 mA output drive at V_DD = 15 V, and supporting logic-level shifting in mixed-voltage interface circuits such as industrial control I/O modules.

For engineers reviewing the CD4504BMG4 datasheet, CD4504BMG4 pinout, CD4504BMG4 application, or CD4504BMG4 equivalent, key selection considerations include its dual-supply operation range, TTL-compatible input thresholds, rail-to-rail output swing, and SOIC-16 package compatibility with legacy 4000-series logic designs.

Technical Context

The CD4504BMG4 implements six independent non-inverting buffer stages with buffered inputs and push-pull outputs, enabling bidirectional voltage-level translation between 5-V TTL and higher-voltage CMOS domains without external components. Its input structure accepts TTL logic levels (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) while driving CMOS loads up to 15 V.

Each buffer features symmetrical propagation delays (t_PLH/t_PHL ≤ 120 ns at V_DD = 15 V, C_L = 50 pF), low quiescent current (I_CC ≤ 1.5 µA at V_DD = 15 V), and latch-up immunity per MIL-STD-883. It operates over –55°C to +125°C, matching military-grade environmental requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	Single: 5 V to 20 V; Dual: ±5 V to ±15 V - enables direct integration into mixed-rail systems without level-shifter ICs.
Input Logic Compatibility	TTL-level inputs (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) - allows direct connection to 5-V microcontroller GPIO or legacy TTL peripherals.
Output Drive Capability	±8 mA at V_DD = 15 V - sufficient to drive multiple 4000-series inputs or small capacitive loads without buffering.
Propagation Delay	≤120 ns (V_DD = 15 V, C_L = 50 pF) - supports reliable timing in sub-MHz digital control and sequencing applications.
Operating Temperature	–55°C to +125°C - qualified for extended industrial and aerospace environments without derating.
Quiescent Current	≤1.5 µA (V_DD = 15 V) - enables use in low-power standby modes of battery-backed or energy-constrained systems.

Pinout & Package

CD4504BMG4 is housed in a 16-pin SOIC (D) package measuring 9.9 mm × 3.91 mm × 1.75 mm (max height), with 1.27 mm lead pitch and RoHS-compliant NiPdAu plating. The package meets JEDEC MO-153 and is rated MSL Level-1 (unlimited floor life).

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (A1–A6)	Buffer input terminals accepting TTL-compatible logic signals; internally protected against transient overvoltage.
2, 4, 6, 10, 12, 14	Output (Y1–Y6)	Push-pull CMOS outputs capable of sourcing/sinking 8 mA; rail-to-rail swing ensures full logic-level fidelity.
7	V_SS	Ground reference for all buffers; must be connected to system common ground for proper noise margin.
16	V_DD	Positive supply terminal; sets output logic high level and defines translation target voltage for all six channels.
8	V_EE	Negative supply terminal (optional); used only in dual-supply mode to extend input/output swing below ground.

Key Features

Feature	Design Value
TTL-to-CMOS level translation	Enables direct interfacing between 5-V TTL logic and 10–15-V CMOS systems without external resistors or translators.
Six independent non-inverting buffers	Provides parallel signal conditioning for multi-channel data paths, such as address/data bus expansion or sensor array readout.
Rail-to-rail output swing	Ensures maximum noise immunity and logic threshold margin when driving downstream CMOS loads at elevated supply voltages.
Wide dual-supply operation (±5 V to ±15 V)	Supports bipolar analog-digital hybrid systems where negative logic rails coexist with positive digital supplies.

Equivalent & Alternatives

The following parts are listed as comparable options for similar level translation and buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4050BM	No TTL input compatibility; requires ≥3.5 V V_IH on 15-V supply - lacks native 5-V TTL interface capability.	Restricted to pure CMOS-to-CMOS translation; unsuitable for direct TTL source connection.	Select CD4050BM only when all upstream logic is CMOS and operates at ≥70% of V_DD.
SN74LVC1G17DBVR	Single-channel, 1.65–5.5 V operation only - no support for >5 V output swing or dual-supply configuration.	Limited to low-voltage portable electronics; cannot replace CD4504BMG4 in high-voltage industrial interfaces.	Choose SN74LVC1G17DBVR only for space-constrained 3.3-V systems needing Schmitt-trigger input hysteresis.

Compared with CD4050BM and SN74LVC1G17DBVR, the CD4504BMG4 uniquely supports TTL input thresholds across 5–20 V operation, delivers rail-to-rail output swing up to 20 V, and integrates six channels in one SOIC-16 package - making it irreplaceable in legacy-mixed-voltage industrial control upgrades.

FAQ

What is the maximum supply voltage rating for CD4504BMG4?

The CD4504BMG4 supports a single-supply range of 5 V to 20 V and a dual-supply range of ±5 V to ±15 V. Absolute maximum ratings specify V_DD–V_SS ≤ 20 V and |V_EE| ≤ 15 V. Exceeding these limits risks permanent damage. The CD4504BMG4 is not rated for 24-V operation, and sustained use above 20 V violates TI's absolute maximum specifications.

Does CD4504BMG4 support true bidirectional level translation?

No, the CD4504BMG4 is a unidirectional non-inverting buffer with fixed input and output terminals. It translates TTL-level inputs to higher-voltage CMOS outputs but does not support reverse signal flow. For bidirectional translation, external circuitry or dedicated bidirectional translators like TXS0108E are required. The CD4504BMG4's architecture enforces strict input→output directionality per channel.

Is CD4504BMG4 pin-compatible with CD4050BM?

Yes, CD4504BMG4 and CD4050BM share identical SOIC-16 pinouts and terminal assignments (inputs on odd pins 1/3/5/9/11/13, outputs on even pins 2/4/6/10/12/14, V_SS on pin 7, V_DD on pin 16). However, CD4504BMG4 adds V_EE on pin 8 for dual-supply operation - leaving it unconnected in single-supply use preserves compatibility with CD4050BM layouts.

What is the input threshold behavior of CD4504BMG4 at 5-V supply?

At V_DD = 5 V, the CD4504BMG4 maintains TTL-compatible input thresholds: V_IL ≤ 0.8 V (guaranteed low) and V_IH ≥ 2.0 V (guaranteed high). This allows direct connection to standard 5-V TTL outputs without pull-up resistors or voltage dividers. The CD4504BMG4's input structure is optimized for this interface, unlike generic CMOS buffers that require ≥3.5 V V_IH at 5-V supply.

Can CD4504BMG4 operate with V_EE grounded in single-supply mode?

Yes, CD4504BMG4 functions correctly with V_EE tied to V_SS (pin 7) in single-supply configurations. Pin 8 (V_EE) is internally isolated from the output stage when unused, and grounding it poses no reliability risk. This configuration is explicitly validated in TI's CD4504B datasheet and commonly deployed in industrial control designs using the CD4504BMG4.
