RD74HC245A - Octal Bus Transceivers

General 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.

Key Features

  • High Speed Operation: tpd = 8 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Ordering Information Part Name RD74HC245APT0 RD74HC245AFPH0 RD74HC245ARPH0 Package Type DILP-20 pin SOP-20 pin (JEITA) SOP-20 pin (JEDEC) Package Code (Previous Code) PRDP0020AC-B (DP-20NEV) PRSP0020DD-B (FP-20DAV) PRSP0020DC-A (FP-20D.

Preliminary Datasheet RD74HC245A Octal Bus Transceivers (with 3-state outputs) Description R07DS0047EJ0100 Rev.1.00 Jul 20, 2010 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 RD74HC245A transfers true data from one bus to the other. This device does not have schmitt trigger inputs.
