Fairchild DM74LS244WM

缓冲器，非反向15mA，24mA4.75V ~ 5.25V

Overview

74LS244, DM74LS244N 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 ransmitters/receivers. ( 74LS244 datasheet )

Features 1.  3-STATE outputs drive bus lines directly 2.  PNP inputs reduce DC loading on bus lines 3.  Hysteresis at data inputs improves noise margins 4.  Typical IOL (sink current) 24 mA 5.  Typical IOH (source current)  -15 mA 6. Typical propagation delay times – Inverting 10.5 ns – Noninverting 12 ns 7. Typical enable/disable time 18 ns 8. Typical power dissipation (enabled) Inverting 130 mW Noninverting 135 mW
