Product Summary

The 74HC240D is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL). The 74HC240D 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.

Parametrics

74HC240D absolute maximum ratings: (1)supply voltage: -0.5 to +7 V; (2)input clamping current: ±20 mA at VI < -0.5 V or VI > VCC + 0.5 V; (3)output clamping current: ±20 mA at VO < -0.5 V or VO > VCC + 0.5 V; (4)output current: ±35 mA at -0.5 V < VO < VCC + 0.5 V; (5)supply current: 70 mA; (6)ground current: 70 mA; (7)storage temperature: -65 to +150 ℃; (8)DIP20 package: 750 mW; (9)SO20, SSOP20, TSSOP20 and DHVQFN20 packages: 500 mW.

Features

74HC240D features: (1)Inverting 3-state outputs; (2)Multiple package options; (3)Complies with JEDEC standard no. 7 A; (4)ESD protection: HBM JESD22-A114-D exceeds 2000 V, MM JESD22-A115-A exceeds 200 V; (5)Specified from -40 ℃ to +85 ℃ and from -40 ℃ to +125 ℃.
