Renesas HD74HC245TELL Octal bus transceivers (with 3-state outputs) Datasheet

HD74HC245
Octal Bus Transceivers (with 3-state outputs)
REJ03D0598–0200
(Previous ADE-205-475)
Rev.2.00
Jan 31, 2006
Description
Each device has an active low enable input G and a direction control input, DIR. When DIR is high, data flows from
the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HC245
transfers true data from one bus to the other. This device does not have schmitt trigger inputs.

2. Waveform– A is for an output with internal conditions such that the
output is low except when disabled by the output control.
3. Waveform– B is for an output with internal conditions such that the
output is high except when disabled by the output control.
4. The output are measured one at a time with one transition per measurement.
