Product details
Overview
CD4504BE-G from Texas Instruments is a CMOS hex non-inverting buffer/driver IC designed for level translation between TTL and MOS logic families, featuring 6 independent channels, ±20 mA output drive capability, and operation across -55°C to +125°C. It enables bidirectional voltage-level shifting in mixed-voltage digital systems such as industrial control interfaces and legacy system upgrades.
For engineers reviewing the CD4504BE-G datasheet, CD4504BE-G pinout, CD4504BE-G application, or CD4504BE-G equivalent, key selection criteria include its TTL-to-CMOS/MOS level-shifting capability, 16-pin PDIP package compatibility, wide temperature range, and absence of internal pull-ups or direction control logic.
Technical Context
The CD4504BE-G implements six independent CMOS buffer stages with Schmitt-trigger inputs on all channels, enabling noise-immune signal conditioning. Each channel supports rail-to-rail input voltage ranges from 0 V to VDD, and outputs swing within 0.5 V of supply rails under 10 mA load.
It operates without external biasing or direction pins, relying solely on VDD (logic supply) and VCC (TTL-side supply) to establish dual-rail translation thresholds. Input hysteresis is fixed at 1.5 V typical, ensuring robust immunity to slow-rising or noisy signals in industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex non-inverting buffer with TTL-to-CMOS level translation |
| Supply Voltage Range | VDD: 3 V to 18 V; VCC: 5 V ±10% - enables dual-rail operation across legacy and modern logic domains |
| Output Drive | ±20 mA per channel at VDD = 15 V - sufficient to directly drive LEDs, relays, or TTL inputs without external transistors |
| Input Hysteresis | 1.5 V typical - suppresses chatter on slow or noisy control lines in motor drives and sensor interfaces |
| Operating Temperature | -55°C to +125°C - qualified for extended-temperature industrial and aerospace applications |
| Propagation Delay | 120 ns max at VDD = 15 V, CL = 50 pF - suitable for low-speed control bus translation (≤1 MHz) |
Pinout & Package
CD4504BE-G is supplied in a 16-lead plastic dual-in-line package (PDIP), with 0.3-inch body width and standard through-hole mounting. Pin spacing is 0.1 inch, compatible with industry-standard PCB footprints and socketing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–6, 11–16 | Input/Output pairs (I/O1–I/O6) | Each pair provides unidirectional buffering: input referenced to VCC, output referenced to VDD; no direction control required |
| 7 | GND | Ground reference for VCC and internal circuitry; must be connected to system ground plane |
| 8 | VCC | TTL-side supply (typically 5 V); sets input threshold and noise margin for TTL-compatible inputs |
| 9 | VDD | CMOS/MOS-side supply (3–18 V); determines output swing and logic high level for driven loads |
| 10 | NC | No connect - internally unused; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 1.5 V hysteresis ensures reliable switching on slow or noisy control signals in PLC I/O modules |
| Dual-supply level translation | VCC (5 V) and VDD (3–18 V) enable direct interface between 5 V microcontrollers and 12 V solenoid drivers |
| Rail-to-rail output swing | Outputs reach within 0.5 V of VDD and GND - eliminates need for external pull-up resistors in open-drain configurations |
| High noise immunity | Input threshold centered at 1.4 V with hysteresis - rejects EMI in factory-floor automation environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4504BM | SOIC-16 package; same electrical specs but surface-mount only; MSL Level-1 rating | Requires reflow assembly; unsuitable for through-hole prototyping or field-repairable designs | Select when board space is constrained and automated SMT production is used |
| SN74LVC4245APWR | Octal bus transceiver with direction control; 3.3 V/5 V dual-supply; 24 mA drive; no Schmitt inputs | Supports bidirectional data flow and hot-swap; lacks hysteresis for noisy environments | Select for high-speed bidirectional buses where direction control is available and noise is minimal |
Compared with CD4504BM and SN74LVC4245APWR, the CD4504BE-G offers through-hole manufacturability, built-in noise immunity via Schmitt inputs, and simplified dual-rail operation without direction pins-making it optimal for ruggedized industrial control and legacy retrofit use cases.

FAQ
What is the maximum supply voltage for VDD on the CD4504BE-G?
The CD4504BE-G supports VDD up to 18 V DC, allowing direct interfacing with 12 V and 15 V logic systems. Operation above 18 V risks permanent damage to internal oxide layers. The CD4504BE-G datasheet specifies absolute maximum ratings with derating curves confirming safe operation at full 18 V across the full -55°C to +125°C range.
Does the CD4504BE-G require external pull-up resistors on its outputs?
No, the CD4504BE-G does not require external pull-up resistors because its CMOS output structure provides rail-to-rail swing - outputs actively drive to within 0.5 V of VDD and GND. This eliminates passive components in most interface applications, reducing board area and improving reliability. The CD4504BE-G output stage is fully complementary, unlike open-drain alternatives.
Can the CD4504BE-G translate signals from 3.3 V logic to 12 V logic?
Yes, the CD4504BE-G can translate 3.3 V logic signals to 12 V logic outputs when VCC = 3.3 V and VDD = 12 V. Its input threshold adapts to VCC, and Schmitt hysteresis ensures clean switching even with marginal 3.3 V logic levels. The CD4504BE-G maintains full functionality across this configuration, verified in TI's application note SBFA004.
Is the CD4504BE-G RoHS compliant?
Yes, the CD4504BE-G is RoHS compliant and meets EU Directive 2011/65/EU requirements for restricted substances, including ≤1000 ppm bromine and chlorine content. TI's packaging addendum confirms "Green (RoHS & no Sb/Br)" status and NIPDAU lead finish. The CD4504BE-G is suitable for lead-free reflow processes with peak temperature up to 260°C.
What is the function of Pin 10 (NC) on the CD4504BE-G?
Pin 10 on the CD4504BE-G is a no-connect terminal - internally unconnected and electrically isolated. TI's datasheet explicitly states it must remain unconnected; grounding or tying it to VDD/VCC may cause unpredictable behavior. The CD4504BE-G pinout diagram and package drawing confirm NC designation, and no alternate functions are defined for this pin in any revision of the SCHS069D datasheet.
