Detailed Description

High-speed TTL-to-ECL unidirectional translator, 6 channels, differential outputs. Single device per package. Surface-mount 28-PLCC/LCC with J-leads. Operates over 0°C to 85°C (TA). Part of the onsemi 100H series for classic ECL systems. Base product number: 100H604. In-stock quantity: 1980 (tube packaging).

Key Features

Function: TTL input to differential ECL output translation

Channels: 6 unidirectional channels (one translator circuit per IC)

Output type: Differential ECL (fast, low-noise signaling)

Input type: TTL-compatible

Series: 100H (high-speed ECL family)

Operating temperature: 0°C to 85°C (TA)

Mounting: Surface mount

Package: 28-PLCC / 28-LCC (J-lead), 11.51 x 11.51 mm

Supplier device package: 28-PLCC (11.51 x 11.51)

Translator type: Mixed-signal logic translator

Key Advantages

Fast propagation with low skew across channels for tight timing

Differential ECL outputs reduce EMI and crosstalk, ideal for high-speed backplanes

Clean TTL input compatibility simplifies interfacing from standard logic

Stable signal integrity and low ground bounce compared to CMOS switching

Compact PLCC footprint with J-leads for robust board-level soldering

Proven 100H family performance for classic ECL infrastructures

Packaging

Shipment form: Tube

Package type: 28-PLCC / 28-LCC (J-lead)

Material: Molded plastic (epoxy) body with copper alloy leads, tin finish (RoHS “G” variant)

Size: 11.51 mm x 11.51 mm body, 28-pin count

Lead style: J-lead for surface-mount, typical pitch 1.27 mm

Pin configuration overview: 6 TTL inputs; 6 differential ECL output pairs; power/ground pins; control pins as defined in datasheet (verify exact pinout there)

Thermal characteristics: Designed for commercial temp range; use good PCB copper area and airflow for heat spreading; consult datasheet for thermal resistance values and derating

Electrical properties (typical use notes):

- TTL input thresholds suited for 5 V logic

- ECL output swing is small and fast for high-speed lines; proper ECL termination required

- High edge rates keep timing tight; use controlled-impedance traces and recommended terminations per datasheet

Lifecycle

Status: Mature, widely used in legacy and ongoing ECL applications. Availability can vary by region and date.

Not currently announced as end-of-life to our knowledge, but the 100H family is long-established. Plan for lifecycle management if deploying in new designs.

Equivalent or alternative models:

- MC10H604FNG (same function in 10H speed grade; pin-compatible family member)

- MC100H604FN (legacy non-RoHS variant; verify availability and compliance)

- If your system uses positive-supply ECL (PECL/LVPECL), consider single-channel translators like MC10ELT23 or MC100LVELT23 and scale channel count as needed (not pin-compatible; verify voltage levels and terminations)

- Multi-channel PECL/LVPECL solutions may be built from multiple single/dual-channel translators (e.g., MC100ELT21/22/23 families), but pinouts, supplies, and terminations differ—check details carefully
