74HCT125D,653 Quadruple bus buffer gate, 3-state outputs, 4.5 ... 5.5 V, SO-14

Quad bus buffer gate with 3-state outputs

Description These bus buffer gates have independent line drivers with 3-status outputs. Each output is disabled if the associated Output Enable (OE) input is high. To ensure the high-resistance condition during power-on or power-off, OE\ should be connected to VCC via a pullup resistor; the minimum value of the resistance is determined by the current-lowering capability of the driver.

Features • Operating voltage range from 4.5 V to 5.5 V. • High-current outputs drive up to 15 LSTTL loads • Low power consumption, 80-µA Max ICC • Typical tpd = 12 ns • ±6 mA output drive at 5 V. • Low input current of 1 µA maximum • The inputs are TTL voltage compatible • High-current outputs with 3 states drive bus lines or buffer memory address registers
