Характеристики
SN74HCT245DWR, АП6The SN74HCT245DWR is an octal Bus Transceiver with 3-state outputs and designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The HCT245 device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
• Inputs are TTL-voltage compatible
• High-current 3-state outputs drive bus lines directly or up to 15 LSTTL loads
• 80µA maximum ICC low power consumption
• 14ns typical Propagation delay (tpd)
• ±6mA Output drive at 5V
• 1µA maximum Low input current
• Green product and no Sb/Br
