Revised August 2000 100325 Low Power Hex ECL-to-TTL Translator General Description Features The 100325 is a hex translator for converting F100K logic levels to TTL logic levels. Differential inputs allow each circuit to be used as an inverting, non-inverting or differential receiver. An internal reference voltage generator provides VBB for single-ended operation, or for use in Schmitt trigger applications. All inputs have 50kΩ pull-down resistors. When the inputs are either unconnected or at the same potential the outputs will go LOW. ■ Pin/function compatible with 100125 When used in single-ended operation the apparent input threshold of the true inputs is 20mV to 40mV higher (positive) than the threshold of the complementary inputs. The VEE and VTTL power may be applied in either order. ■ Meets 100125 AC specifications ■ 50% power reduction of the 100125 ■ Differential inputs with built in offset ■ Standard FAST outputs ■ 2000V ESD protection ■ −4.2V to −5.7V operating range ■ Available to industrial grade temperature range Ordering Code: Order Number Package Number Package Description 100325SC M24B 24-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 100325PC N24E 24-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-010, 0.400 Wide 100325QI V28A 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square 100325QC V28A 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square Industrial Temperature Range (−40°C to +85°C) Devices also available in Tape and Reel.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The “Recommended Operating Conditions” table will define the conditions for actual device operation.
