texas instruments SN54LS245 SN74LS245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS handbook
SN54LS245 and SN74LS245 are octal bus transceivers with 3-state outputs. They can drive bus lines directly, PNP inputs reduce dc loading on bus lines, and hysteresis at bus inputs improves noise margins. The typical propagation delay time is 8 ns. The document also includes ordering information for the product.
