FEATURES * Wide supply voltage range from 1.65 to 3.6 V * Complies with JEDEC standard: JESD8-7 (1.65 to 1.95 V) JESD8-5 (2.3 to 2.7 V) JESD8B/JESD36 (2.7 to 3.6 V). * 3.6 V tolerant inputs/outputs * CMOS LOW power consumption * Direct interface with TTL levels (2.7 to 3.6 V) * Power-down mode * Latch-up performance exceeds 250 mA * ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C. SYMBOL tPHL/tPLH PARAMETER propagation delay inputs An to Bn; Bn to An CONDITIONS VCC = 1.8 V; CL = 30 pF; RL = 1 k VCC = 2.5 V; CL = 30 pF; RL = 500 VCC = 2.7 V; CL = 50 pF; RL = 500 VCC = 3.3 V; CL = 50 pF; RL = 500 CI CI/O CPD input capacitance input/output capacitance power dissipation capacitance per buffer VCC = 3.3 V; notes 1 and 2 outputs enable outputs disabled Notes 1. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = total load switching outputs; (CL x VCC2 x fo) = sum of the outputs. 2. The condition is VI = GND to VCC. DESCRIPTION
74ALVC245
The 74ALVC245 is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. The 74ALVC245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74ALVC245 features an output enable input (OE) for easy cascading and send/receive input (DIR) for direction control. OE controls the outputs, so that the buses are effectively isolated.
