Product Attributes

Description: The 74LS240 is anOctal Buffer/Line Driver with 3-State Outputs from the TTL logic family of products from Texas Instruments (TI). Features: Outputs Source/Sink 24 mA Supply Voltage Range 4.75V to 5.25V Wide Operating Temperature Range -55°C to 125°C Inputs TTL Compatible Outputs Triple 3-State Open Collector Outputs Output-Enable Control +24mA/-24mA Output Drive Capability ESD Protection Exceeds 2000V Per MIL-STD-883, Method 3015.7 Application: Multiplexers Bus Drivers Data Acquisitions Process Control Interfacing to 5V Environments (For reference only)

General Description

These buffers/line drivers are designed to improve both the performance and PC board density of 3-STATE buffers/ drivers employed as memory-address drivers, clock drivers, and bus-oriented transmitters/receivers. Featuring 400 mV of hysteresis at each low current PNP data line input, they provide improved noise rejection and high fanout outputs and can be used to drive terminated lines down to 133Ω.

Features

● 3-STATE outputs drive bus lines directly

● PNP inputs reduce DC loading on bus lines

● Hysteresis at data inputs improves noise margins

● Typical IOL(sink current) 24 mA

● Typical IOH(source current) -15 mA

● Typical propagation delay times

- Inverting 10.5 ns

- Noninverting 12 ns

● Typical enable/disable time 18 ns

● Typical power dissipation (enabled)

- Inverting 130 mW

- Noninverting 135 mW
