PRODUCTION DATA documents contain information current as of publicationdate. Products conform to specifications per the terms of Texas Instrumentsstandard warranty. Production processing does not necessarily include testingof all parameters.
These bus buffers feature three-state outputs that, when enabled, havethe low impedance characteristics of a TTL output with additional drive capabilityat high logic levels to permit driving heavily loaded bus lines without externalpull-up resistors, when disabled, both output transistors are turned off presentinga high-impedance state to the bus so the output will act neither as a significantload nor as a driver. The '125 and 'LS125A outputs are disabled when G ishigh. The 126 and 'LS126A outputs are disabled when G\ is low.
