74VHC245 Octal Bidirectional Transceiver with 3-STATE Outputs November 1992 Revised March 1999 74VHC245 Octal Bidirectional Transceiver with 3-STATE Outputs General Description The VHC245 is an advanced high speed CMOS octal bus transceiver fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHC245 is intended for bidirectional asynchronous communication between data busses. The direction of data transmission is determined by the level of the T/R input. The enable input can be used to disable the device so that the busses are effectively isolated. All inputs are equipped with protection circuits against static discharge. Features s High Speed: tPD = 4.0 ns (typ) at VCC = 5V s High Noise Immunity: VNIH = VNIL = 28% VCC (Min) s Power Down Protection is provided on all inputs s Low Noise: VOLP = 0.9V (typ) s Low Power Dissipation: ICC = 4 µA (Max) @ TA = 25°C s Pin and Function Compatible with 74HC245 Ordering Code: Order Number 74VHC245M 74VHC245SJ 74VHC245MTC 74VHC245N Package Number M20B M20D MTC20 N20A Package Description 20-Lead Small Outline Integrated Package (SOIC), JEDEC MS-013, 0.300” Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Surface mount packages are also available on Tap...
