Low Power Octal ECL/TTL Bi-Directional Translator with Latch
100328 Low Power Octal ECL/TTL Bi-Directional Translator with Latch April 1989 Revised August 2000 100328 Low Power Octal ECL/TTL Bi-Directional Translator with Latch General Description Features The 100328 is an octal latched bi-directional translatorIdentical performance to the 100128 at 50% of the designed to convert TTL logic levels to 100K ECL logic lev- supply current els and vice versa. The direction of this translation is deter-Bi-directional translation mined by the DIR input. A LOW on the output enable input 2000V ESD protection (OE) holds the ECL outputs in a cut-off state and the TTL Latched outputs outputs at a high impedance level. A HIGH on the latch enable input (LE) latches the data at both inputs evenFAST TTL outputs though only one output is enabled at the time. A LOW on3-STATE outputs LE makes the 100328 transparent. Voltage compensated operating range = −4.2V to −5.7V The cut-off state is designed to be more negative than a Available to industrial grade temperature range normal ECL LOW level. This allows the output emitter-fol- lowers to turn off when the termination supply is −2.0V, pre- senting a high impedance to the data bus. This high impedance reduces termination power and prevents loss of low state noise margin when several loads share the bus. The 100328 is designed with FAST TTL output buffers, featuring optimal DC drive and capable of quickly charging and discharging highly capacitive loads. All inputs have 50 kΩ pull-down resistors.
