What are the key features of SN74ABT2245NE4?
- Octal 8-bit bidirectional bus transceiver with common direction control supports seamless A-to-B and B-to-A data transfers on a single device
- ABT-family outputs source 32 mA and sink 64 mA, driving heavily loaded 50 pF bus lines at speeds up to 200 MHz
- 3-state outputs with active-HIGH output enable allow multiple transceivers to share one bus without contention
What is SN74ABT2245NE4 used for?
SN74ABT2245NE4 is suited for 8-bit data bus interfacing in embedded processor systems where a 20-pin DIP footprint is preferred for prototyping or through-hole assembly. The device bridges 5 V TTL buses in backplane designs and industrial control boards that require bidirectional level conversion with direction-control logic. Its high output-current capability makes it a practical buffer for driving long PCB traces or cable loads in test equipment.

Frequently Asked Questions
How much output drive current does SN74ABT2245NE4 provide and why does it matter for bus loading?
SN74ABT2245NE4 can sink up to 64 mA and source up to 32 mA per output. This high drive capability allows it to charge or discharge 50 pF bus capacitance quickly, sustaining signal edge rates fast enough to support data transfers at up to 200 MHz without excessive signal ringing on 5 V TTL bus lines.
Can SN74ABT2245NE4 replace an older 74245 device in an existing through-hole design?
SN74ABT2245NE4 is pin-compatible with standard 74245 octal bus transceivers in a 20-pin DIP package (JEDEC R-PDIP-T20). Its ABT-family switching speeds are faster than original 74LS or 74HC equivalents, but the 5 V supply requirement and 1.27 mm pin pitch are identical, allowing a drop-in substitution. Output current is also higher at 64 mA sink versus 24 mA in 74LS245.
What control pins does SN74ABT2245NE4 use to set data direction and enable the outputs?
The device has two control inputs: a direction (DIR) pin and an output-enable (OE, active-LOW) pin. When DIR is HIGH, data flows from A to B; when DIR is LOW, data flows from B to A. Pulling OE HIGH disables all 8 output drivers to a high-impedance 3-state condition, allowing up to 120 bus nodes to share the same 8-wire data path.
Which applications benefit most from SN74ABT2245NE4 compared to an ABT245 in a surface-mount package?
Prototyping boards, educational kits, and legacy industrial equipment with 2.54 mm through-hole layouts benefit most. Surface-mount variants like SN74ABT245ADWR save 60% board space, but where through-hole soldering is required for mechanical robustness or hand-assembly without SMT tooling, the 20-pin DIP of SN74ABT2245NE4 is preferred. Both variants share the same 5 V rail and 64 mA sink current.
