INTEGRATED CIRCUITS 74LV245 Octal bus transceiver (3-State) Product specification Supersedes data of 1997 Feb 19 IC24 Data Handbook 1998 Apr 20 Philips Semiconductors Philips Semiconductors Product specification Octal bus transceiver (3-State) 74LV245 FEATURES Wide operating voltage: 1.0 to 5.5 V Optimized for low voltage applications: 1.0 to 3.6 V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Output capability: bus driver ICC category: MSI QUICK REFERENCE DATA GND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns SYMBOL tPHL/tPLH CI CI/O CPD PARAMETER Propagation delay An to Bn; Bn to An Input capacitance Input/output capacitance Power dissipation capacitance per buffer Tamb = 25°C Tamb = 25°C DESCRIPTION The 74LV245 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT245. The 74LV245 is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The 74LV245 features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated.
