Product details

Overview

CD4504BEG4 from Texas Instruments is a CMOS hex level shifter designed to translate logic levels between TTL/DTL-compatible inputs (0–5 V) and CMOS outputs (up to 18 V), supporting bidirectional voltage translation across six independent channels. It operates over –55°C to +125°C, features low quiescent current (1.5 mA max), and is housed in a 16-lead PDIP package.

For engineers reviewing the CD4504BEG4 datasheet, CD4504BEG4 pinout, CD4504BEG4 application, or CD4504BEG4 equivalent, this device is selected for high-voltage interface bridging in mixed-supply systems where logic-level compatibility, wide temperature operation, and discrete channel isolation are critical design requirements.

Technical Context

The CD4504BEG4 implements six independent CMOS transmission-gate-based level shifters, each with separate input (A), output (B), and supply (V_CC/V_DD) terminals. It requires dual supplies: V_SS = 0 V (ground), V_DD = 5 V (input logic reference), and V_CC = up to 18 V (output logic rail).

Each channel supports unidirectional or bidirectional translation depending on external biasing; no internal direction control logic is present. Input thresholds are TTL-compatible (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V at V_DD = 5 V), and output drive capability is specified for capacitive loads up to 50 pF.

Key Specifications

Logic Function	Hex non-inverting level shifter with independent channel control
Input Voltage Range	0 V to V_DD (5 V typical); TTL/DTL-compatible thresholds
Output Voltage Range	0 V to V_CC (up to 18 V); enables interface with higher-voltage logic or analog circuitry
Supply Configuration	Three-rail: V_SS = 0 V, V_DD = 5 V, V_CC = 5–18 V
Quiescent Current	1.5 mA max at V_CC = 15 V, V_DD = 5 V - ensures low static power in battery-backed or thermally constrained systems
Operating Temperature	–55°C to +125°C - qualified for extended industrial and automotive under-hood environments
Package Type	16-lead PDIP (N), 0.300-inch width - compatible with through-hole prototyping and legacy industrial PCBs

Pinout & Package

CD4504BEG4 is supplied in a 16-lead plastic dual-in-line package (PDIP-N) with 0.300-inch body width and standard through-hole lead spacing. Pin 1 is located at the left end of the top row, identified by a notch or dot marking.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (A1–A6)	TTL/DTL-compatible logic inputs referenced to V_DD
2, 4, 6, 10, 12, 14	Output (B1–B6)	CMOS-level outputs referenced to V_CC, capable of driving 50-pF loads
7	V_SS	Ground reference for all internal circuitry and input logic
8	V_DD	5-V logic supply for input stage and internal biasing
16	V_CC	High-voltage supply (5–18 V) for output stage and level-shifting transistors
15	NC	No connect - internally unused; must be left floating or tied to V_SS per layout guidelines

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar level-shifting applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4504BMG4	Same die, SOIC-16 package (8.65 mm × 3.91 mm); surface-mount; RoHS-compliant NiPdAu finish	Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair	Select CD4504BMG4 when board space, reflow compatibility, or production scalability are primary constraints.
SN74LVCH16T245DGGR	16-bit dual-supply bus transceiver; 1.65–3.6 V A-side / 1.65–5.5 V B-side; no support for >5.5 V outputs	Limited to low-voltage translation only; cannot replace CD4504BEG4 in 12-V or 15-V output applications	Choose SN74LVCH16T245DGGR only for high-density, low-voltage bidirectional data buses-not for high-voltage actuator control.

Compared with CD4504BMG4, CD4504BEG4 offers through-hole mechanical robustness and legacy system compatibility; compared with SN74LVCH16T245DGGR, it uniquely supports up to 18-V output translation-making it irreplaceable in high-voltage industrial interface designs.

FAQ

What is the maximum output voltage supported by the CD4504BEG4?

The CD4504BEG4 supports an output supply voltage (V_CC) up to 18 V, enabling direct interface with 12-V and 15-V logic or analog subsystems. This specification is confirmed in the Absolute Maximum Ratings table of the TI datasheet SCHS069D, and applies across the full operating temperature range of –55°C to +125°C. The CD4504BEG4 must not be operated above 18 V on V_CC, as permanent damage may occur.

Is the CD4504BEG4 pin-compatible with other CD4504B variants like CD4504BMG4?

Yes, the CD4504BEG4 is pin-compatible with CD4504BMG4 and all other CD4504B family members, including CD4504BPWR and CD4504BF3A. All share identical 16-pin functional mapping and electrical behavior. The only differences are package type (PDIP vs. SOIC vs. TSSOP), marking, and thermal/mechanical characteristics - no PCB layout changes are required when substituting CD4504BEG4 for CD4504BMG4 in existing designs.

Does the CD4504BEG4 support bidirectional level shifting?

The CD4504BEG4 supports bidirectional translation per channel when externally biased with appropriate pull-up/pull-down networks on both A and B sides, but it does not contain internal direction control circuitry. Its core architecture is six independent transmission gates - directionality is determined entirely by external voltage sources and load conditions. This differs from dedicated bidirectional translators like the TXB0108, which integrate auto-sensing logic.

What is the recommended decoupling for the CD4504BEG4?

TI recommends placing a 0.1-µF ceramic capacitor between V_CC and V_SS, and another 0.1-µF capacitor between V_DD and V_SS, located within 5 mm of the respective pins on the CD4504BEG4. These capacitors suppress supply noise generated during output switching transitions and ensure stable level-shifting performance, especially under heavy capacitive loading or fast edge rates.

Can the CD4504BEG4 be used with 3.3-V microcontrollers?

Yes, the CD4504BEG4 accepts 3.3-V logic inputs when V_DD is set to 3.3 V, provided the input voltage thresholds remain within specification (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V). However, its input stage is optimized for TTL/DTL compatibility at 5 V; for guaranteed 3.3-V operation, verify noise margins using the VIH/VIL curves in Figure 4 of the SCHS069D datasheet. The CD4504BEG4 output side remains fully functional at any V_CC from 5 V to 18 V regardless of V_DD.
