Key Features
- 6-channel unidirectional TTL/CMOS-to-CMOS translation with push-pull outputs enabling direct interfacing between 5 V TTL and high-voltage CMOS logic up to 15 V
- 280 ns maximum propagation delay ensuring reliable signal timing in mixed-logic industrial and military-grade system designs
- Ceramic DIP-16 package (JESD-30 R-GDIP-T16) providing superior thermal performance and long-term reliability for harsh-environment applications
Applications
The CD4504BF3A is used in industrial and legacy system upgrades where 5 V TTL logic boards must drive or be driven by 3 V to 15 V CMOS peripherals, translating signal levels across 6 channels simultaneously in a single 16-pin device. Its ceramic DIP package makes it well-suited for military, aerospace, and high-reliability industrial applications where plastic packages are unsuitable due to thermal cycling or moisture exposure. The push-pull output architecture ensures clean, low-impedance output transitions that reduce susceptibility to noise in long signal paths and backplane interconnects.

Frequently Asked Questions
How does the CD4504BF3A handle level translation between 5 V TTL and 12 V CMOS logic in a legacy industrial system?
The CD4504BF3A accepts standard TTL-level inputs from a 5 V logic source and shifts them to a CMOS output level determined by the VDD supply, which can be set anywhere from 3 V to 15 V including 12 V CMOS. All 6 channels translate simultaneously with a 280 ns maximum propagation delay, allowing direct connection between a 5 V TTL bus and a 12 V CMOS peripheral without discrete resistor networks or dual-supply op-amp circuits.
For a military-grade electronics design, what advantage does the ceramic DIP package of the CD4504BF3A provide over plastic alternatives?
The ceramic DIP-16 (JESD-30 R-GDIP-T16) package withstands temperature cycles from -55 °C to 125 °C and humidity exposure that causes plastic packages to delaminate or crack over time. Hermetic ceramic construction is required in many MIL-STD-883 and defense procurement specifications, making the CD4504BF3A directly usable in avionics, military communications, and harsh industrial environments where plastic SO or TSSOP alternatives are explicitly excluded.
When should a designer use the CD4504BF3A instead of a bidirectional level translator for a 6-channel bus interface?
The CD4504BF3A is the correct choice for strictly unidirectional signal paths—such as a microcontroller driving display or actuator control lines—where the 280 ns delay is acceptable and no back-channel data is needed. Bidirectional translators add complexity, higher cost, and potential bus contention risk when direction control is mismanaged; using the unidirectional CD4504BF3A eliminates direction-control logic and simplifies firmware, provided all 6 channels always carry signals in the same direction.
