SN54126 - QUADRUPLE BUS BUFFERS

Download the SN54126 datasheet PDF. This datasheet also covers the SN54125 variant, as both devices belong to the same quadruple bus buffers family and are provided as variant models within a single manufacturer datasheet.

General Description

These bus buffers feature three-state outputs that, when enabled, have the low impedance characteristics of a TTL output with additional drive capability at high logic levels to permit driving heavily loaded bus lines without external pullup resistors.

When disabled, both output transistors are turned off, presenting a high-impedance state to the bus so the output will act neither as a significant load nor as a driver.
