Product Summary

The 74HC244; 74HCT244 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL).
The 74HC244; 74HCT244 has octal non-inverting buffer/line drivers 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 74HC244;74HCT244 is identical to the 74HC240; 74HCT240 but has non-inverting outputs.

Parametrics

Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to
GND (ground = 0 V):
(1)supply voltage -0.5 +7 V; (2)input clamping current VI < -0.5 V or VI > VCC + 0.5 V: ±20 mA; (3)output clamping current VO < -0.5 V or VO > VCC + 0.5 V:±20 mA; (4)output current, VO = -0.5 V to (VCC + 0.5 V): ±35 mA; (5)quiescent supply current: 70 mA; (6)ground current:70 mA; (7)storage temperature :-65 +150 ℃; (8)total power dissipation,SOP20:500 mW

Features

(1)Octal bus interface; (2)Non-inverting 3-state outputs; (3)Complies with JEDEC standard no. 7A; (4)ESD protection:HBM EIA/JESD22-A114-C exceeds 2000 V;MM EIA/JESD22-A115-A exceeds 200 V; (5)Multiple package options; (6)Specified from -40 °C to +85 °C and from -40 °C to +125 °C
