Product Summary

The 74HCT244D is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). The 74HCT244D 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 74HCT244D is identical to the 74HC240, but 74HCT240 has non-inverting outputs.

Parametrics

74HCT244D absolute maximum ratings: (1)tPHL/ tPLH propagation delay, CL = 15 pF; VCC = 5 V:11 ns; (2)CI input capacitance:3.5 pF; (3)CPD power dissipation capacitance per buffer: 35 pF.

Features

74HCT244D 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 2000V; (5)Multiple package options; (6)Specified from -40℃ to +85℃ and from -40℃ to +125℃.
