7 / 14 page Philips Semiconductors Product specification 74LV259 8-bit addressable latch 1998 May 20 7 AC CHARACTERISTICS (Continued) GND = 0V; tr = tf ≤ 2.5ns; CL = 50pF; RL = 1KΩ SYMBOL PARAMETER WAVEFORM CONDITION –40 to +85 °C –40 to +125 °C UNIT SYMBOL PARAMETER WAVEFORM VCC(V) MIN TYP1 MAX MIN MAX UNIT 1.2 –20 t Hold time Figure 6 2.0 5 –7 5 ns th An to LE Figure 6 2.7 5 –5 5 ns 3.0 to 3.6 5 –42 5 NOTES: 1. Unless otherwise stated, all typical values are measured at Tamb = 25°C 2. Typical values are measured at VCC = 3.3 V. AC WAVEFORMS VM = 1.5 V at VCC ≥ 2.7 V and ≤ 3.6V; VM = 0.5 × VCC at VCC < 2.7 V and ≥ 4.5 V. VOL and VOH are the typical output voltage drop that occur with the output load.
