74HC240; 74HCT240
General description
The 74HC240; 74HCT240 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL).
The 74HC240; 74HCT240 is a dual octal inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state.
The 74HC240; 74HCT240 is similar to the 74HC244; 74HCT244 but has inverting outputs.
Features
- Inverting 3-state outputs
- Multiple package options
- Complies with JEDEC standard no. 7 A
- ESD protection:
- HBM JESD22-A114-D exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
- Specified from -40 Cel to +85 Cel and from -40 Cel to +125 Cel
